The synthesis of $$3-octyne$$ is achieved by adding a bromoalkane into a mixture of sodium amide and an alkyne. The bromoalkane and alkyne respectively are:

A$$BrCH_{2}CH_{2}CH_{2}CH_{3}$$ and $$CH_{3}CH_{2}C\equiv CH$$
B$$BrCH_{2}CH_{2}CH_{3}$$ and $$CH_{3}CH_{2}CH_{2}C \equiv CH$$
C$$BrCH_{2}CH_{2}CH_{2}CH_{2}CH_{3}$$ and $$CH_{3}C\equiv CH$$
D$$BrCH_{2}CH_{2}CH_{2}CH_{3}$$ and $$CH_{3}CH_{2}C\equiv CH$$
Correct Answer

Solution


$$A$$ will give 3-nonyne.

$$B$$ will give 4-octyne.

$$C$$ will give 2-octyne.

$$D$$ will give 3-octyne.

Hence, the correct answer is $$D$$.
