Detailed Solution

p-Nitrophenol is more acidic than m-nitrophenol and o-nitrophenol.
The electron withdrawing group NO2 stabilizes phenoxide ion through –R effect at para and ortho position.
NO2 group in meta position will show –I effect.
Presence of NO2 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.
