Asserion: Lucas reagent is a micture of ...

Asserion: Lucas reagent is a micture of anhydrous `ZnCI_(2)` and concentrate `HCI`.
Reaon: Primary alcohol produces ppt. with Lucas reagents.

A

If both assertion and reason are true and the reason is the correct explanantion of the assertion.

B

If both assertion and reason are true but reason is not the correct explanantion of the asseriton.

C

If assertion is true but reason is false.

D

If assertion if false but reason is ture.

Text Solution

Verified by Experts

The correct Answer is:
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.
