A dihaloalkane 'X' having formula \[{{C}_{3}}{{H}_{6}}C{{l}_{2}},\]on hydrolysis gives a compound that can reduce Tollens' reagent. The compound 'X' is

A)  1, 2-dichloropropane

B)  1, 1-dichloropropane

C)  1, 3-dichloropropane

D) 2, 2-dichloropropane.

Correct Answer: B

Solution :

[b] :.As the obtained compound reduces Tollens' reagent, it must be an aldehyde. Thus, it is obvious that both the -Cl atoms are present at C - 1. Hence, the compound 'X? is 1, 1-dichloropropane and the reactions are as follows:
