The atomicity of white phosphorus is X ...

The atomicity of white phosphorus is `X` and the `P-P-P` bond angle is `Y`. What are `X` and `Y` ?

A

`X = 4, Y = 90^@`

B

`X = 4, Y = 60^@`

C

`X = 3, Y = 120^@`

D

`X = 2, Y = 180^@`

Text Solution

Verified by Experts

The correct Answer is:
B
`P_4` exists as tetrahedra tetratomic discrete molecule with `P-P-P` bond angle of `60^@`, hence atomicity of `P = 4`.
