Vedclass · Answer

(A) To determine the hybridization of the central atom,we use the formula: $	ext{Steric Number} = (	ext{Number of sigma bonds}) + (	ext{Number of lone pairs})$.$1$. For $SO_2$: The central atom $S$ has $2$ sigma bonds and $1$ lone pair. $	ext{Steric Number} = 2 + 1 = 3$,which corresponds to $sp^2$ hybridization.$2$. For $NO_2^-$: The central atom $N$ has $2$ sigma bonds and $1$ lone pair. $	ext{Steric Number} = 2 + 1 = 3$,which corresponds to $sp^2$ hybridization.$3$. For $N_3^-$: The central atom $N$ has $2$ sigma bonds and $0$ lone pairs. $	ext{Steric Number} = 2 + 0 = 2$,which corresponds to $sp$ hybridization.Therefore,the hybridizations are $sp^2, sp^2$ and $sp$ respectively.

In $SO_2$,$NO_2^-$ and $N_3^-$ the hybridizations at the central atom are respectively $:$
