Question

select the correct value for the indicated bond angle in each of the following compounds:

Answer 1

For O3, it will have an angle of <120. There are three bonding domains on the central O. 2 bonds and one lone pair. So you start with a bond angle of 120, but the lone pair takes up a little more space than the bonds. so the angle is a little less than 120. 

SCl2 will be <109.5. There are 4 bonding domains on S (2 bonds and 2 lone pairs). So the angle starts at 109.5 but due to lone pairs, it is less (similar to a water molecule) 

SOCl2 will be <109.5 similar to SCl2 but 3 bonds and one lone pair on eh central atom.

SOCl2 will be <109.5 similar to SCl2 but 3 bonds and one lone pair on eh central atom.
