Bond Angle

Postby Chiara Berruto 1K » Mon Jun 04, 2018 6:55 pm

How do you determine the exact bond angle? I understand that based of lone pairs we can determine whether or not an angle will be less than 109.5 but is there a way to know the exact angle/ make a close estimate or do you have to look up the number.

Exact bond angles cannot be obtained from VSEPR. Exact bond angles are obtained from experimental data.

When determinong bond angles we can only guess that they areless than the accepted amounts when lone pairs are present.

In the notes he gave us the number of degrees for each type of angle/vsepr model. You should review the notes and try to memorize them!!

The absolute exact bond angle is not necessary to know because they are different for every molecule, knowing the general angles (like either 109.5 or <109.5) is good enough because exact angles require experimental data.
