Choose the correct statement(s).

(A) True: the $-M$, $-I$ nitro group stabilises the phenoxide ($\mathrm{p}K_a\approx7.15$), phenol has $\mathrm{p}K_a\approx10.0$ and the electron-donating methyl group destabilises the phenoxide in $p$-cresol ($\approx10.26$). (B) True: $o$-nitrophenol has intramolecular hydrogen bonding, so it is not associated and is steam volatile, whereas $p$-nitrophenol is intermolecularly hydrogen bonded. (C) False: in water, solvation of the ammonium ion governs the order, which is $(\mathrm{CH_3})_2\mathrm{NH}>\mathrm{CH_3NH_2}>(\mathrm{CH_3})_3\mathrm{N}$ ($\mathrm{p}K_b=3.27,\ 3.38,\ 4.22$); trimethylamine is the weakest because it has only one N-H for hydrogen bonding to solvent. (D) False: delocalisation of the nitrogen lone pair into the ring makes it less available, so aniline ($\mathrm{p}K_b\approx9.4$) is a much weaker base than benzylamine ($\mathrm{p}K_b\approx4.7$). Hence (A) and (B).
