Halide of the elements of group thirteen, and

Text Solution

Verified by Experts

The correct Answer is:
`AX_3`- Valency of group 13 is 3 and of halogen is 1.
Valency of group 13 elements is 3.
Valency of halogens is 1.

So, the molecular formula of halide of group thirteen elements is `MX_3` where M is the group 13 element and X is halogen.
