Show Answer
Solution:
- (c) Phenols are more acidic than alcohols as they are resonance stabilised whereas alcohols are not.
Further $-NO_2$ is an electron withdrawing group which increases acidic character and facilitates release of proton, whereas $-CH_3$ is an electron donating group which decreases acidic character, thus removal of $H^{+}$becomes difficult.
