1.	Which of the following will dissolve in aqueous Na_(2)CO_(3) ?
Answer» PHENOL 2,4,6-Trimethylphenol 2,4,6-Trinitrophenol 2,4-Dinitrophenol Solution :Phenol is less ACIDIC than `H_(2)CO_(3)`. As such phenol does not dissolve in aqueous `Na_(2)CO_(3)`. However, PRESENCE of electron WITHDRAWING group `(-NO_(2))` makes it more acidic. Thus 2, 4-dinitrophenol and 2,4,6-trinitrophenol are more acidic than `H_(2)CO_(3)` and as such dissolve in `Na_(2)CO_(3)` to diaplce weaker acid `H_(2)CO_(3)`.
