Chloroethene is treated with sodium amide in liquid ammonia. The major product isA. acetyleneB. ethenamineC. sodium ethynideD. 2-chloroethenamine

Answer» Correct Answer - C
`CH_2=CH-Clunderset(NH_3)overset(NaNH_2)toCH-=CHunderset(NH_3)overset(NaNH_2)toCH_3-=overline(C)Na^(+)+NH_3`
Sodamide in liquid ammonia is a strong base. Thus, it causes the dehydrochlorination of chloroethene to give acetylene. Being acidic in nature, it reacts with `NaNH_2` to form sodium acetylide.
