Question

How many optically active alcohols of molecular formula $C_6{H}_{13}O$ give instant white turbidity with Lucas reagent?

Answer 1

No active alcohols of molecular formula $C_6{H}_{13}O$ will give instant white turbidity with Lucas reagent. Lucas reagent is a mixture of anhydrous zinc chloride and $HCl$. it converts alcohols to alkyl chlorides which results in turbidity. Tertiary alcohols give turbidity immediately, secondary alcohols give turbidity in 3 to 5 minutes and primary alcohols gives turbidity only on heating.
