Bond Angles

Postby AronCainBayot2K » Sun Nov 17, 2019 3:16 pm

How would you determine the angle of a bond and know that it should be lower than a specific type of angle bond? For example, if a molecule is trigonal planar, we would need to know that the bond angles would be exactly 120 degrees?

You must memorize the bond angles for the various shapes, but if dealing with lone pairs, that will cause the bond angle to be less than expected because the lone pairs will cause the atoms to be closer together.

You don't need to know the exact angle in these cases, just if it's less or more than the expected angle.
