Answer 2

ETHYNE CAN BE CONVERTED TO HEX-3-YNE BY REACTING IT WITH 2 EQUIVALENT OF $NaNH_{2}$ AND 2 MOLES OF ETHYL BROMIDE.

Explanation:

• Sodium amide is an excellent base it takes up the terminal hydrogen atom from alkynes. So, when ethylene will be reacted with sodium amide($NaNH_{2}$) it will take its terminal hydrogen atom and will form a acetylide ion. Then we will react it with ethyl bromide($C_{2}H_{5} Br$) and it will form butyne.
• Then butyne will again be reacted with another equivalent of sodium amide($NaNH_{2}$), and then with ethyl bromide($C_{2}H_{5} Br$) to form hex-3-yne.
