Question

What is the final product of reaction?
$CH_{3} -C \equiv CH \xrightarrow{Na} \,\,\,\,\,\xrightarrow{CH_{3}-CH_{2} -1}$Product

• A. $CH_{2} = CH -CH_{2} - CH_{3}$
• B. $CH_{3} - CH_{2} - C \equiv C - CH_{2} - CH_{3}$
• C. $CH = C - CH_{2} - CH_{2} - CH_{3}$
• D. $CH_{3} - C \equiv C - CH_{2} - CH_{3}$

Answer 1

Answer: (D)

$CH_{3}-C \equiv CH \xrightarrow{Na} CH_{3}-C \equiv C -Na^{+} \xrightarrow[S_{N^{2}}]{CH_{3}-CH_{2}-1}$
$CH_{3}- C \equiv C -C H_{2} -CH_{3}$
