(i) Addition of water in acidic medium to propene yields propan-2-ol and not propan-1-ol. This is due to the formation of more stable intermediate 2° carbocation instead of the less stable 1° carbocation as the reaction proceeds in normal acidic condition. This is because it follows Markovnikoff’s Rule of addition.
(ii) Phenols give 2,4,6-trinitrophenol(Picric acid) when it reacts with a mixture of conc. HNO3 and H2SO4.
