seesaw

[JChen_2I]

Are the angles of a seesaw molecule 90 and 120 degrees? Or should they be slightly less than 90 and 120.
The textbook answer key says it should be 90 and 120 exactly, but shouldn't the lone pair repulsion cause the angles to be slightly smaller?

Hi! I think it is less than 90 degrees and 120 degrees.

[Natalie Wang 1B]

I asked my TA, and he said that the angles will be less than 120 and 90.

Due to the repulsion of the lone pairs, they should be less than 90 and 120.

they should be slightly less than 90 and 120 degrees as the lone pair causes the angle to be less and not 90 and 120 degrees exactly

The repulsion of the lone pairs will cause the bond angles to be slightly less than 90 and 120 degrees.
