Question

When `2-` butyne reacts with sodamide in an inert solvent in the presence of dilute `HCl` , the product formed is `:`
A. `n-`butane
B. `2-`Butene
C. `1-`Butyne
D. `1-`Propyne

Answer 1

Correct Answer - c
When `2-` butyne is heated with `NaNH_(2)` in an inert solvent, the sodium derivative of but`-1-`yne which is converted into but `-1-`yne by the action of dil. `HCl`.
`CH_(3)-C-=C-CH_(3)+NaNH_(2)overset(Parafi n e)rarr NH_(3)+CH_(3)CH_(2)C-=CNa overset(dil. HCl)rarr underset(1-butyn e)(CH_(3)CH_(2)C-=CH`
