Question

convert the ethyne to butiyne​

Answer 1

Explanation:

Higher alkynes are made from lower alkyne.

When ethyne is treated with sodium acetylide it gives acetylide.

Step 1:  CH\equiv CH+NaNH_2\rightarrow HC\equiv C^-Na^+

Reaction of acetylide with chloro ethane will give us butyne as a product.

Step 2:

Reaction of acetylide with chloro ethane will give us butyne as a product.
