Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Key Idea As the number of lone pairs of electrons increases, bond angle decreases due to repulsion between lp-lp. Moreover, as the electronegativity of central atom decreases, bond angle decreases. Hence, the order of bond angle is
( $\mathrm{Cl}$ is less electronegative as compared to $\mathrm{O}$.)
