`CH_3C-=CH+Cu+CuClunderset(O_2.CH_3OH)overset(NH_3)to`
identify the product.

A

`CH_3CH=CH-CH=CHCH_3`

B

`CH_3C-=C Cu`

C

`CH_3C-=C-C-=C CH_3`

D

`CH_3CH=CH-C-=C CH_3`

Text Solution

Verified by Experts

The correct Answer is:
C
Cuprous acetylides undergo oxidative coupling when heated in organic solvent in the presence of air:
`CH_3C-=CHunderset(NH_3)overset(CuCl)toCH_3C-=CC u`
`2CH_3C-=C C uoverset(O_2)toCH_2C-=C-C-=C CH_3`
