Question
Assertion (A): Bromination of benzoic acid, gives m-bromobenzoic acid.
Reason (R): Carboxyl group increases the electron density at the meta position.
Options
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.
Solution
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.
