Q. In which of the following molecules the central atom does not have sp3 hybridization?
A) CH₄
B) SF₄
C) BF₄⁻
D) NH₄⁺
Explanation
[Solution from source] SF₄ has 4 bond pairs and 1 lone pair on S (5 electron pairs), so S is sp³d with a see-saw shape. CH₄, BF₄⁻ and NH₄⁺ all have four electron pairs and are sp³. Answer (2).
