P-methylbenzoic acid is more reactive than p-methylanisole towards incoming electrophiles.
Accepted Answer
This statement is true. p-Methylbenzoic acid is more reactive than p-methylanisole towards incoming electrophiles. Here's why:
Electron-withdrawing groups: The carboxylic acid group (-COOH) in p-methylbenzoic acid is an electron-withdrawing group. It pulls electron density away from the benzene ring, making the ring more electron-deficient. This makes the ring more susceptible to attack by electron-rich electrophiles.
Electron-donating groups: The methoxy group (-OCH3) in p-methylanisole is an electron-donating group. It pushes electron density towards the benzene ring, making the ring more electron-rich. This makes the ring less susceptible to attack by electron-rich electrophiles.
