Question

A mixture of two organic chlorine compounds was treated with sodium metal in ether solution. Isobutane was obtained as a product. The two chlorine compounds are.

• A. Methyl chloride and propyl chloride
• B. Methyl chloride and ethyl chloride
• C. Isopropyl chloride and methyl chloride
• D. Isopropyl chloride and ethyl chloride

Answer 1

Answer: (C)

Isopropyl chloride and methyl chloride

Answer 2

$\underset{\text{Isopropylchloride}}{CH_{3} - \underset{\underset{CH_{3}}{|}}{CH} - Cl} + 2Na + \underset{\text{Methylchloride}}{Cl - CH_{3}}\underset{\text{Ether}}{\overset{\quad\text{Dry}\quad}{\rightarrow}}$

$\underset{\text{Isobutane}}{CH_{3} - \underset{\underset{CH_{3}}{|}}{CH} - CH_{3}} + 2NaCl$
