Nitrogen forms N(2) but phosphorous when...

Nitrogen forms `N_(2)` but phosphorous when forms `P_(2)` gets readily converted into `P_(4)` because

A

triple bond is present between phosphorus atoms

B

`p pi -d pi ` bonding is weak

C

`p pi- p pi` bonding is strong

D

multiple bond is formed easily.

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(2)` is unstable because the `p pi -d pi ` bonding in it is weak. It is due to larger atomic size of P and N. thus `P_(2)` is converted into `P_(4)` in which there is no `p pi -dpi` bonding.
