Seesaw Shape

Postby Duby3L » Sat Nov 17, 2018 2:12 am

Would the bond angles for the Seesaw shape be 90,120,180. If so, would all the bond angles be slightly less than that of the trigonal bipyramidal?

Yep, that is correct. All angles will be slightly less than 90, 120, and 180 due to the lone pair repulsion.

Yes all the bond angles would be less than 90,120,180 because the lone pair is more repulsive and the bond angles are pushed further away.

Yeah but they will be just slightly less than those angles, but for approximation thats right.

For the Test do we have to put the exact bond angle when it is slightly less?
For example for AX3E it is slightly less than 109.5, it is 107. For the Test do have to put that the bond angle is 107 or is it okay to say it is slightly less than 109.5.
