Detailed Solution

p-Nitrophenol is more acidic than m-nitrophenol and o-nitrophenol.
The electron withdrawing group $- N O_{2}$ stabilizes phenoxide ion through –R effect at para and ortho position.
$- N O_{2}$ group in meta position will show –I effect.
Presence of $- N O_{2}$ group at ortho position it form hydrogen bonding with –OH group.
Hence, acidity is less than p-nitrophenol order of acidic strength.
p-nitrophenol > o-nitrophenol > m-nitrophenol Ethanol will not give immediate turbidity with Lucas reagent.
$3 °$ alcohol will give white turbidity immediately statement I is true but statement II is false.
