Fun Chemistry: Bromine Water Test, Alcohols, and Esters for Kids

Olivia Churcher

@oliviachurcher

Learn about the bromine water test to easily spot the difference between saturated and unsaturated compounds—like in butter and cooking oil! Find out if phenol is saturated or unsaturated, and explore cool properties and types of alcohols from simple notes. Get to know how esters form, their uses, and the magical esterification process. Perfect for curious young minds who love chemistry!

Systematic Carbon Chemistry

This page covers the fundamental concepts of saturated vs unsaturated compounds in higher chemistry.

Key points:

Saturated compounds contain single carbon-carbon bonds
Unsaturated compounds have at least one carbon-carbon double bond
Bromine water is used to distinguish between saturated and unsaturated compounds
Factors affecting solubility and boiling point are discussed

Definition: Saturated compounds are molecules with only single bonds between carbon atoms, while unsaturated compounds contain at least one double or triple bond between carbon atoms.

Example: Unsaturated compounds quickly decolorize bromine water from orange to colorless, while saturated compounds do not.

Vocabulary: Isomers are compounds with the same molecular formula but different structural formulae.

Alcohols

This page focuses on the properties and types of alcohols, which are important Higher Chemistry functional groups.

Key points:

Alcohols contain a hydroxyl $-OH$ functional group
They are polar molecules capable of hydrogen bonding
Alcohols are soluble in water and have high melting and boiling points
Types of alcohols: primary, secondary, and tertiary

Definition: Alcohols are organic compounds containing a hydroxyl $-OH$ group attached to a carbon atom.

Example: Ethanol $CH₃CH₂OH$ is a primary alcohol commonly found in alcoholic beverages.

Highlight: The ability of alcohols to form hydrogen bonds contributes to their unique properties, such as higher boiling points compared to alkanes of similar molecular mass.

Carboxylic Acids

This page discusses the properties and reactions of carboxylic acids, another important class of organic compounds.

Key points:

Carboxylic acids contain a carboxyl $-COOH$ functional group
They are polar molecules capable of hydrogen bonding
Carboxylic acids are soluble in water and react with metal oxides, hydroxides, and carbonates

Vocabulary: The carboxyl group $-COOH$ is the functional group that defines carboxylic acids.

Example: Vinegar is an aqueous solution of ethanoic acid $CH₃COOH$ .

Highlight: When carboxylic acids react with bases, they form salts with names ending in "-anoate".

Esters

This page covers the formation, properties, and uses of esters, which are derived from alcohols and carboxylic acids.

Key points:

Esters contain an ester link functional group
They are formed by reacting an alcohol with a carboxylic acid
Esters are used as flavoring agents and industrial solvents
The formation of esters is a condensation reaction, while their breakdown is hydrolysis

Definition: Esters are organic compounds formed by the reaction between an alcohol and a carboxylic acid, characterized by the ester link functional group.

Example: Methyl ethanoate can be formed by reacting methanol with ethanoic acid.

Highlight: The process of making esters in the lab involves using sulfuric acid as a catalyst and a water bath for heating, as the mixture is flammable.

Fats and Oils

This page discusses the structure, properties, and importance of fats and oils in chemistry and biology.

Key points:

Fats and oils are concentrated energy sources and essential for vitamin transport
They are non-polar molecules with different melting points
Fats and oils are naturally occurring esters made from glycerol and fatty acids
Fats are saturated, while oils are unsaturated

Definition: Fats and oils are triglycerides, consisting of three fatty acid molecules attached to a glycerol backbone through ester bonds.

Example: The systematic name for glycerol is propan-1,2,3-triol.

Highlight: Oils can be hardened by reacting with hydrogen over a nickel catalyst, making them more saturated and solid at room temperature.

Soaps and Detergents

This page explains the chemistry behind soaps and detergents, including their structure, function, and production.

Key points:

Soaps are water-soluble salts of fatty acids
Alkaline hydrolysis is used to produce soaps from edible fats or oils
Soap molecules have a polar, hydrophilic head and a non-polar, hydrophobic tail
The cleaning action of soaps is explained step-by-step
Hard water can cause problems with soap effectiveness
Soapless detergents are an alternative to traditional soaps

Definition: Soaps are water-soluble salts of fatty acids, typically produced by the alkaline hydrolysis of fats or oils.

Example: The structure of a soap molecule includes a carboxylate head $COO⁻Na⁺$ and a long hydrocarbon tail.

Highlight: Soapless detergents contain a sulfonate ion instead of a carboxylate ion, making them more effective in hard water.

Emulsions

This page introduces the concept of emulsions, which are mixtures of two immiscible liquids.

Key points:

Emulsions contain small droplets of one liquid dispersed in another immiscible liquid

Definition: An emulsion is a mixture of two or more liquids that are normally immiscible, where one liquid is dispersed in the other as small droplets.

Example: Milk is an example of a natural emulsion, where fat globules are dispersed in water.

Unit 2: Nature's Chemistry

This page introduces Unit 2 of a chemistry course, focusing on Nature's Chemistry. It sets the stage for exploring organic compounds and their properties.

Highlight: This unit delves into the chemistry of carbon-based compounds found in nature and their synthetic counterparts.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Best app on earth! no words because it’s too good

Thomas R

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

Basil

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

Greenlight Bonnie

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

Rohan U

Android user

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

Elisha

iOS user

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
