Lucas test is given by an alcohol within 5 minutes, 0.22 g of which liberates 56 mL of CH4 at STP

Question 1

Lucas test is given by an alcohol within 5 minutes, 0.22 g of which liberates 56 mL of CH4 at STP on treating with CH3MgI. The structure of alcohol is

Question 2

The correct option is: (b)

Explanation:

Lucas test will be given by all the given alcohols within 5 minutes as all are 2° alcohols. Exact structure can be known by molecular mass or formula of alcohol which will be obtained as follows: Let molecular mass of alcohol be M.

The general formula of alcohols is CnH2n+1OH.

The molecular mass 88 corresponds to the value of n = 5. Thus, the 2° alcohol is (CH3)2CHCHOHCH3.
