Vedclass · Answer

(A) In $PH_3$,the phosphorus atom is $sp^3$ hybridized,but the three $P-H$ bonds are formed by the overlap of $p$-orbitals of phosphorus with $s$-orbitals of hydrogen.Due to the presence of a lone pair on the phosphorus atom and the lack of significant hybridization,the bond angle is very close to $90^o$.The actual bond angle $H-P-H$ in $PH_3$ is approximately $93^o$.

The bond angle in $PH_3$ would be expected to be close to ............. $^o$.
