Question

in a regular octahedral molecule MX6 the number of X-M-X bonds at 180degree is?

Answer 1

The correct answer is 3.

In a normal octahedral structure of MX₆, 3 bonds of X-M-X can be formed that pass through each other at the centre.

Thus, 3 bonds with 180° angle can be formed by crossing each other at the centre.
