Question

The number of π - bonds present in C₂ (Vap.) molecule according to molecular orbital theory are ______.

Options

• 2

• 6

• 10

• 5

Answer 1

The number of π - bonds present in C₂ (Vap.) molecule according to molecular orbital theory are 2.

Explanation:

The configuration of C₂ molecule according to Molecular orbital theory is

`"KK" [sigma(2"s")]^2 [sigma(2"s")]^2 [(pi 2 "px")]^2 [pi 2 "py"]^2`

As two π MO are filled. ∴ Two π-bond.
