Acetylene underset(O2)overset(Cu^(2+)to ...

Acetylene `underset(O_2)overset(Cu^(2+)to` The product formed in the reaction is

A

`HC-=C-C-=CH`

B

`H_2C=CH-C-=CH`

C

`H_2C=CH-CH=CH_2`

D

`CH_3C-=C CH_3`

Text Solution

Verified by Experts

The correct Answer is:
A
Under oxidative conditions, acetylenic copper compounds undergo coupling to form the dimer:
`HC-=CHoverset(Cu^(2+))toHC-=C-Cuoverset(O_2)toHC-=C-C-=CH`
