Question

What is the hybridization of phosphine?

• A. $sp$ hybridized
• B. $s{p}^2$ hybridized
• C. $s{p}^3$ hybridized
• D. No hybridization

Answer 1

The correct option is D No hybridization

The hybridization of phosphine seems like $s{p}^3$ but in reality the molecule has no hybridization as it forms all bonds using its pure $p$-orbitals. This can be proved from its bond angle data which shows that its bond angles are ${93}^{\circ }$.
