Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Basic structure

Steric number = 6

Hybridization = sp³d²

Shape = octahedral

(A) Maximum atoms in one plane is 5 (Correct)

In octahedral geometry:

4 atoms in square plane + 1 opposite atom can lie in a plane

Total = 5 atoms

(B) Type of overlapping sp³d³–p (Incorrect)

The correct hybridization is sp³d², NOT sp³d³.

So, the overlap is sp³d² – p.

(C) Total number of triangular faces are 8 (Correct)

An octahedron has 8 triangular faces.

(D) Total number of edges are 6 (Incorrect)

An octahedron has 12 edges, not 6.
