Phenol is less acidic than (1) acetic acid (2) p-methoxyphenol (3) p-nitrophenol (4) ethanolA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: D
Solution :
Carboxylic acids are stronger acids than phenol. Presence of electron withdrawing group \[(N{{O}_{2}})\]in p-nitrophenol makes it more acidic than phenol. Alcohols are weaker acids than phenol. Presence of electron donating group (methoxy) in p-methoxyphenol makes it less acidic than phenol.
