I don’t usually find this for most educational videos, but your explanation is so clear. Everything makes perfect sense. Thank you!

Thank's so much for making this video! I just watched my lecturer explain the same thing, but wasn't understanding the seesaw shape until I watched this! You explain it perfectly and thoroughly! I look forward to referring to more of your videos for help.

This helped me understand electron domains and molecular geometry so much better! Thanks.

Why in the AX3E2 case are the non-bonding pairs arranged in an equatorial and not axial position? In the axial position each non-bonding pair interacts with 4 other domains, three of which are at 90° and one at 180°. In equatorial position, however, it has 2 interactions at 90° but two at 120°. So I wonder why one interaction at 90 and one at 180 are not better than two at 120 also considering that with the first configuration the two non-bonding pairs would be as far apart as possible? In molecules like ClF3 a planar trigonal geometry seems more sensible to me rather than a "T" one.

Do you happen to know if the method based on counting sigma bonds and subtraction 1 to predict hybridization is true for every compound? Or it fails in particular cases?
For example: CH4 - 4 sigma bonds - 1 = 3 (sp^3)
CO2 - 2 sigma bonds - 1 = 1 (sp)
