Bond Angles

Postby Malia Shitabata 1F » Wed Nov 13, 2019 10:10 pm

For a molecule with a trigonal planar shape, how do we know if it's 120º, less than 120º, or 109.5º?

For trigonal planar shapes, all bond angles are 120 degrees.

For trigonal planar, if all of the atoms attached to the central atom are the same then the bond angle will be 120. A smaller atom on one of the bonds would make the angles smaller and a larger atom than the rest would make them larger. Hope this helps!
