Question
Assertion $(A): 4-$nitrophenol is more acidic than $2, 4, 6-$trinitrophenol.
Reason $(R):$ Phenol is a weaker acid than carbonic acid.
✓

Answer

Electron withdrawing groups such as $-NO_2, CN, - X,$ increase the acidity. Greater the number of electron-withdrawing groups more is the acidic character, $i.e. 2, 4, 6-$trinitrophenol is more acidic than $4-$nitrophenol.
