Consider the following species :
1. `[O_(2)]^(2-)` 2. `[CO]^(+)` 3. `[O_(2)]^(+)`
Among these sigma bond alone is present in

A

1 alone

B

2 alone

C

3 alone

D

1 and 2

Text Solution

Verified by Experts

The correct Answer is:
A
`because` Among the given species, all are dil-atomic species. Only `[O_(2)]^(2-)` contain one `sigma` bond between two bonded atoms.
`therefore` (a) is the correct option.
