1) what's the difference between V shaped and bent?
I think they are the same but my note says V shaped is <120 and bent is <109.5 degree
from trigonal planar, if one of the X is electron pairs, that's bent.
trigonal planar is 120 degree. Since electrons take more spaces, I thought it's safe to say it's <120 but the note says <109.5. hm....
2)seesaw is >90
shouldn't it be smaller than 90 since electrons pairs at the top take more spaces and push them down?
trigonal bipyramid had 90 degree. When one of the X atom from the T shaped structure of trigonal bipyramid is electron pairs, it becomes seesaw. Since electron pairs take more spaces than regular X atom, it should push the other two of the T shape down. When these two are pushed down, the angle between these and 2 legs should be less than 90.
3) square pyramid is >90
I think it should be smaller than 90 for the same reason I described above.
E is electron pairs. Since it takes more spaces than X at the top, all the other 4 X on the side should go toward top and so the angle between these 4 and the X at the top should be less than 90 in my opinion.
