Question

A molecule, that is sp3d2 hybridized and has a molecular geometry of square pyramidal, has ________ bonding groups and ________ lone pairs around its central atom a molecule, that is hybridized and has a molecular geometry of square pyramidal, has ________ bonding groups and ________ lone pairs around its central atom 5, 1 4, 2 4, 1 3, 2 2, 3

Answer 1

Answer: The correct answer is 4, 2.

Explanation:

Hybridization is calculated by using the formula:

$\text{Number of electron pairs} =\frac{1}{2}[V+N-C+A]$

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

It is given that the hybridization of a molecule is $sp^3d^2$, this means that the number of electron pairs are 6. The molecular geometry of the molecule having electron pairs as 6 is octahederal.

If the molecular geometry of the molecule is square pyramidal, then it would acquire 4 electron pairs as the bonding groups and the rest pairs would be considered as lone pairs.

Hence, the correct answer is 4, 2.
