question_answer

An organic compound \[A({{C}_{4}}{{H}_{9}}Cl)\] on reaction with Na/diethyl ether gives a hydrocarbon which on monochlorination gives only one chloro derivative then, A is:                      [AIPMT 2001]

A) t-butyl chloride

B) sec- butyl chloride

C) iso butyl chloride

D) n-butyl chloride

Correct Answer: A

Solution :

[a] Alkyl halides reacts with Na in presence of dry ether to form alkanes is known as Wurtz reaction

In the given question \[{{C}_{4}}{{H}_{9}}CI\] is the t-butyl chloride \[(-4)\]. It reacts with Na in dry ether to form a hydrocarbon that on chlorination gives only one monochloro derivative.

(It gives only one type of mono chloro derivative)
