Question

An organic compound $A(C_4 H_9 C1)$ on reaction with Na/diethyl ether gives a hydrocarbon which on monochlorination gives only one chloro derivative, then A is

• A. t-butyl chloride
• B. s-butyl chloride
• C. iso-butyl chloride
• D. n-butyl chloride

Answer 1

Answer: (A)

t-butyl chloride

Answer 2

Alkyl halides reacts with Na in presence of dry ether to form alkanes. This reaction is known as Wurtz reaction .In the given question $C_4 H_9 C1$ is the t-butyl chloride A. It reacts with Na in dry ether to form a hydrocarbon that on chlorination gives only one monochloro derivative.
2,2, 3, 3-tetra mehnyl-butane (It gives only Qne type of monochloro derivative.)
