The bond angle in

\mathrm{P}{\mathrm{H}_3}

is:

View answer and explanation

Correct option: A

Much lesser than

\mathrm{N}{\mathrm{H}_3}

Option A (Much lesser than

\mathrm{N}{\mathrm{H}_3}

) is correct because the bond angle in

P{H_3}

is closer to 90 degrees due to less s-character in the bonding orbitals compared to

N{H_3}
