What is the geometry of dichloromethane?? Before optimization, Cl-C-Cl bond is 109.5, H-C-Cl bond is 67.8... so it must be tetrahedral... but after optimization, do the angles get bigger?? why?

and also, the bond length increases...

Why do angles and the bond length in dichloromethane increase when it's geometrically optimized??

Another question is...

when we examine (E)-1,2-diisopropylethene, (Z)-diisopropylethene, and 1,1-diisopropylethene... the molecular energies are different. (E) isomer has the least energy, so it's more stable and the 1,1-isomer's the least stable... i think...? why??? does it have to do with how the bulky groups are far apart or not??

The most confusing part!!! is how the bond angle for these isomers are in a weird order.... E has the smaller angle, and Z has the biggest.... I can't figure out why!!! > . <
