Predict the shape of nh3 and pcl3

NH3 is Ammonia that is having 3 Hydrogens attached.

It has 1 unbonded electron bond and 3 sigma bonds thus these four regions make Ammonia as sp3 hybridized.

The shape of NH3 is Trigonal pyramidal there is one atom in the middle and three others at the corners and those 3 molecules are identical

PCl3 is having Trigonal pyramidal structure

It has the same bond angle possessed by Ammonia, lone pair of the electron is one
