The compound shown gives turbidity with the Lucas reagent immediately at room temperature. Which of the structures shown gives turbidity only after about five minutes at room temperature?

AStructure A
BStructure B
CStructure C
DStructure D

Answer: C

Lucas reagent (

ZnCl X_{2}

/conc. HCl) gives immediate turbidity with tertiary alcohols, turbidity in about 5 minutes with secondary alcohols and none at room temperature with primary alcohols. Butan-2-ol (C) is secondary; A, B and D are primary.
