Solution

We are tasked with determining the bond angle of the given compounds. For this purpose, we shall employ the same approach that we use in identifying the molecular geometry of a compound. We will refer to the VSEPR table shown below.



We can answer this problem by answering following these key steps: 

Step 1: Determine the central atom in this molecule. 

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule. 

Step 4: Determine the shape of the molecule/arrangement of all the electron pairs in a way that minimizes repulsions.
