Type: Assertion Reason-conceptual-Medium-Class 12
Assertion: Aniline does not undergo Friedel-Crafts reaction. Reason: Friedel-Crafts reaction is an electrophilic substitution reaction.
A
If both assertion and reason are true and reason is the correct explanation of assertion.
B
If both assertion and reason are true but reason is not the correct explanation of assertion.
C
If assertion is true but reason is false.
D
If both assertion and reason are false.
Correct Answer
Option B
Detailed Explanation
Aniline does not undergo Friedel-Crafts reaction due to salt formation with aluminium chloride, the Lewis acid, which is used as a catalyst. Due to this, nitrogen of aniline acquires a positive charge and hence acts as a strong deactivating group for further reaction.
