In a regular octahedral molecule `MX_(6)` the number of `X - M - X` bonds at `180^(@)` is

A

Six

B

Four

C

Three

D

Two

Verified by Experts

The correct Answer is:

C

In octahedral molecule six hybrid orbitals are directed towards the corner of a regular octahedron with a bond angle of `90^@`.

according to this geometry, the number of`X - M - X` bond at 180° must be three.
