Answer 1

Correct Answer - C
Lucas reagent is a mixture of anhydrous `ZnCI_(2)` and conc. `HCI` is used for the distinction of monohydric alcohol. Tertiary alcohols on addition produce a precipiate immediately while secondary alcohols produce ppt. after `5` minutes. Primary alcohols do not product any precipiate. Therefore, asserion is ture but reason is false.
