Unlike phenol, 2,4-dinitrophenol is soluble in sodium carbonate solution in water because
- presence of two—NO2 groups in the ring makes 2, 4-dinitrophenol a stronger acid than phenol
- presence of two —NO2 groups in the ring makes 2, 4-dinitrophenol a weaker acid than phenol
- presence of two —NO2 groups make the hydrogen bonding easier, making 2, 4-dinitrophenol soluble
- nitro group reacts with Na2CO3 while —OH group does not.
Answer
(A) presence of two—NO 2 groups in the ring makes 2, 4-dinitrophenol a stronger acid than phenol
