Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(A) Total number of lone pair in a molecule is one (Incorrect)

Br has 1 lone pair.

But F atoms also have lone pairs (3 each).

So total lone pairs in whole molecule ≠ 1.

That’s why this option is wrong.

(B) Maximum number of atoms in a plane are four (Correct)

4 F atoms form a square plane.

(C) Maximum number of planes containing maximum atoms are three (Correct)

Different planes can include 4 atoms (square base combinations).

(D) d orbitals used are d(z²) and d(x²–y²) (Correct)

For sp³d² hybridization, these two d orbitals are used.
