Which of the following diatomic molecular species has only `pi` bonds according to Molecular orbital Theory

A

`Be_(2)`

B

`O_(2)`

C

`N_(2)`

D

`C_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`C_(2):(sigma1s)^(2)(sigma^(**)1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(pi2p_(x))^(2)=(pi2p_(y))^(2)`
It has only `pi-` bonds.
