Synthetic Routes and Reaction Pathways

Synthetic routes are the step-by-step pathways chemists use to convert one organic compound into another. Think of them as recipes that show you exactly how to get from your starting material to your desired product.

The flowchart shows how aliphatic compounds $straight-chain organic molecules$ can be transformed through various reactions. Each arrow represents a specific reaction with particular reagents and conditions needed to make the conversion work.

Alkanes sit at the centre as the most basic hydrocarbon structure. From here, you can create haloalkanes using halogens under UV light, or move to alkenes through elimination reactions using strong acids like H₃PO₄ or H₂SO₄ with heat.

The beauty of these pathways is their interconnectedness. Alcohols can be oxidised to aldehydes $using distillation with K₂Cr₂O₇/H₂SO₄$ or ketones (using reflux conditions), whilst these carbonyl compounds can be reduced back using NaBH₄ or H₂/Ni.

Quick Tip: Primary alcohols oxidise to aldehydes then carboxylic acids, whilst secondary alcohols only oxidise to ketones - remember this pattern for your exams!

Carboxylic acids and their derivatives (esters, amides, acyl chlorides) form another important family. You can make esters from carboxylic acids using alcohols with concentrated H₂SO₄, or create amides via acyl chlorides with ammonia or primary amines.

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.

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.
