Question

Explain the non-linear shape of $H_{2}S$ and non-planar shape of $PC{l}_3$ using valence shell electron pair repulsion theory.

Answer 1

In both $H_{2}S$ and $PC{l}_3$, lone pairs are present along with bond pairs around the central atom. According to VSEPR, theory L.P-L.P > L.P-B.P > B.P.-B.P. Therefore, shapes are different.
