Question

An organic compound $A\left(C_3{H}_{7}Cl\right)$ on reaction with Na/diethyl ether gives a hydrocarbon which on monochlorination gives only two chloro derivative, then A is

• A. tertiary butyl chloride
• B. isobutyl chloride
• C. secondary butyl chloride
• D. isopropyl chloride

Answer 1

The correct option is D isopropyl chloride

An organic compound A $\left(C_3{H}_{7}Cl\right)$ on reaction with Na/diethyl ether gives a hydrocarbon which on monochlorination gives only two chloro derivative then, A must be isopropyl chloride. The reaction of isopropyl chloride chloride with Na/diethyl ether to form 2,3-dimethylbutane is an example of Wurtz reaction. The product 2,3-dimethylbutane has two type of H atom which is replaced with chlorine to give two monochloro derivative.


Hence, the correct answer is option (d).
