Question

What is the hybridization of interhalogen compounds of the type XX’5(Square pyramidal)?

(a) sp^3d^2

(b) sp^2d^2

(c) sp^4d^3

(d) sp^3d^3

This question was addressed to me in an interview for internship.

The question is from P-Block Elements topic in section P-Block Elements of Chemistry – Class 12

Answer 1

The correct option is (a) sp^3d^2

The explanation is: The structure of all interhalogen compounds of the type XX’5 involves sp^3d^2 hybridization of the central halogen atom X and hence have octahedral (also called square pyramidal) geometry and with one position occupied by a lone pair.
