Seesaw Shape

Postby Jordan Young 2J » Tue Nov 19, 2019 3:03 pm

For atoms that have a seesaw molecular shape, I know that you select one of the equatorial angles to be the lone pair. So does that mean that the bond angles for seesaw shaped molecules is 90 degrees, 180 degrees, and <120 degrees? If not, what are the bond angles for a seesaw shaped molecule?

The lone pair in the seesaw shaped molecule affects all angles in the molecule. So the bond angles will be <90 degrees and <120 degrees.

The bond angles for the seesaw model are always less than 90 and less than 120 due to the presence of lone pairs.

The bond angles will be >180, 90, and <120 because the lone pairs exerts repulsive forces on the atoms.

The bond angles would be <90, <120, and >180 degrees because the lone pair has a stronger repulsive force than the bond.

any tips on how to easily calculate the angles? or are we better off memorizing them?

Seesaw shape only has >90 and >120 bond angles.

It would be easier to just memorize them. The seesaw shape would be <90 and <120 degrees

The angle would be <90.

The angle would be less than 90 for axial, and less than 120 equatorial.

The bond angles for the seesaw molecule will be slightly less than 90 and 120 degrees, since the lone pair affects the bonding angles.
