Question

Assertion (A): Bromination of benzoic acid, gives m-bromobenzoic acid.

Reason (R): Carboxyl group increases the electron density at the meta position.

पर्याय

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

• Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is true, but Reason (R) is false.

• Assertion (A) is false, but Reason (R) is true.

Answer 1

Assertion (A) is true, but Reason (R) is false.

Explanation:

m-bromobenzoic acid is produced by brominating benzoic acid. As an electron-withdrawing group, −COOH reduces electron density in a π system, making it more electrophilic and directing the incoming group to the meta position. The −COOH group decreases electron density in the ortho and para positions while increasing electron density in the meta position.
