NEET Chemistry Substitution Reactions Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): Halogens are considered moderately deactivating groups in aryl halides. | Reason (R): Halogens increase the overall electron density on the benzene ring through resonance.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option C
Detailed Explanation
Halogens are moderately deactivating because they reduce the overall electron density on the benzene ring, making substitution difficult. Resonance increases electron density on specific positions but not the overall density.
