What shape and bond angles would this molecule have in three dimensions?

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

Explanation :

In the given molecule, 'Y' is the central atom and 'X' is the neighboring atom. In the given molecule, there are 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 shape and bond angle of the given molecule is, bent and respectively.

the answer is definitely c.
