Question

24. Which of the following aryl amines undergoes diazotisation most readily?
Explanation please!​

Answer 1

From the given aryl amine, the one that undergoes diazotization most readily is (1).

• In the first option, the withdrawing nature of the NO₂ group leads to diazotization most readily.

• Diazotization can be defined as the process of conversion of primary aromatic amines into its diazonium salt.

• These salts can then undergo coupling reactions to form azo dyes.

Answer 2

Answer:

OPTION (3)

Explanation:

-OCH3 being a +R group, increases the electron density at nitrogen , therefore it can undergo diazotisation more easily

I'll break it down more simpler :

+R group (electron donating) groups increase basiscity and -R vice versa , and diasotisation is mainly a process that happens in a basic environment, so we need a basic substrate , which can be provided by our electron donating friend -OCH3 group.

Here's a tip : go and study the electron withdrawing and donating group order from GOC , when attending questions like (acidity , basicity , nucleophilicity etc.) this , choose the odd one out as the rest three will be the opposite (in our case rest three are electron withdrawing group) .That will save time during your competetive exams

All the best

and Happy learning !!
