Question
Unlike phenol, 2, 4-dinitrophenol is soluble in sodium carbonate solution in water because
A.
presence of two $$ - N{O_2}$$ groups in the ring makes 2, 4-dinitrophenol a stronger acid than phenol
B.
presence of two $$ - N{O_2}$$ groups in the ring makes 2, 4-dinitrophenol a weaker acid than phenol
C.
presence of two $$ - N{O_2}$$ groups make the hydrogen bonding easier, making 2, 4-dinitrophenol soluble
D.
nitro group reacts with $$N{a_2}C{O_3}$$ while $$-OH$$ group does not.
Answer :
presence of two $$ - N{O_2}$$ groups in the ring makes 2, 4-dinitrophenol a stronger acid than phenol
