Question

Which of the following molecule consists
a hybrid orbital with zero 's' orbital
character
(A) CH4
(B) SF
(C) SF
(D) IF​

Answer 1

Answer:

(b) sf is the right option

Answer 2

Molecule which consists of a hybrid orbital with zero 's' orbital is none of the given option

• Let's examine all given molecules one by one

A) CH4

• CH4 is a tetrahedral compound

$hybridization \: = sp {}^{3}$

• Therefore s character present in this molecule is 25%

B) SF

• There is no such molecule with formula SF.

C) IF

• Expected hybridization of IF is $sp{}^{3}$ due to the presence of three lone pairs and one bond pair.

• Thus, s character in IF is also 25%
