10 Tips and Tricks to Crack JEE Main Exam

1. Haloalkanes can give you every possible functional group. They can also help you in increasing the chain size. So you might want to convert your starting material to haloalkanes and then go to the desired product.

2. Remember the series of oxidation/reduction: Hydrocarbons (with various substituents) can be oxidised to alcohols, then appropriate carbonyl compounds and lastly carboxylic acids (or their derivatives)

3. Strong oxidising agents are KMnO4 and K2Cr207.

4. Mild oxidising agents depending on the situation are Cro4, Ammoniacal AgNO3, Benedicts Solution, Fehling’s solution, Cu or CuO at 573K, Bromine water etc.

5. Any carboxylic acid derivative can be converted back to carboxylic acid by hydrolysis.

6. There are possibilities of hydride and methyl to get the most stable intermediate (carbocation/free radical).

7. The most common reaction, if your starting material is an alkane, is free radical halogenation.

8. Saytzeff/markonikov rules must be kept in mind while dealing with alkenes (they are based on the electron displacement effects only)

9. Decarboxylation and ozonolysis could go to methods for decreasing the number of carbon atoms.

10. Grignard reagent gives you the much-needed Alkyl nucleophile, which can be used at appropriate places.
