Answer : The molecular geometry and bond angle of the given molecule is, bent and respectively.

Explanation :

As we are given that, 'X' is the central atom and 'Y' is the neighboring atom and 'Z' represents lone pairs on the central atom. The given molecule is, .

In the given molecule, there are 2 bond pairs of electrons and 2 lone pairs of electrons. Thus, there are total 4 electron pairs that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.

But as there are two atoms around the central atom, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent or angular and the bond angle will be, .

Hence, the molecular geometry and bond angle of the given molecule is, bent and respectively.
