Explain the non-linear shape of `H_(2)`S and a non-planer shape of `PCl_(3)` using valence shell elecilron pair repuJsion theory.

Explanation

Central atom do this is S.
There are 6 electrons in its valence shell `(""_(16)S = 2, 8, 6 )`.
From this two electrons are shared with two H-atoms and the remaining four electrons are present as two lone pairs.

So, total pairs of electrons are four (2 bonding pairs and 2 lone pairs).
As the presence of 2 lone pairs the shape becomes distorted tetrahedral or angular or bent (non-linear).

`PCl_(3)` : Central atom is phosphorus. There are 5 electrons in its valence shell (`""_(15)`P = 2, 8, 5). Three electrons are shared with three 0 -atoms and the remaining two elecirons are present as one lone pair.
So, total pairs of electrons are four (1 lone pair and 3 bond pajrs). Due to the presence of one lone pair, the shape becomes pyramidal (non- planar).
