Bond angles

[AlyssaRivera]

Should we memorize bond angles for different structures? If so, which are the most important to memorize?

To be honest, I think it would be a good idea to try and memorize all of the bond angles of the molecular shapes just to be safe.

The VSEPR formula really helps with determining the shape and bond angles!

Something I used to help memorize is once you get the basic shapes down (ones without lone pairs), once you get to the shapes with lone pairs, the bond angles are similar but for exmaple
A trigonal planar is AX3 and an angular shaped molecule is AX2E. Both have three regions of electron density. Trigonal planar is 120 degrees and angular ones are usually >120 degrees. Most of them follow this trend.

For shapes that are <x, should we memorize the estimations of the bond angles?
