bond angles

Postby annaspain » Fri Nov 09, 2018 2:52 pm

Will the bond angles for a specific molecular shape always be the same for that shape regardless of what elements make it up? For example, BF3 has a trigonal planar shape and bond angles of 120 degrees each. Will another molecule with this trigonal planar shape also have bond angles of 120 degrees?

I think the bond angles just depend on the covalent bonds and lone pairs.

lone pairs take up more space/ repel bonds more so it will change the measured bond angles.

I believe that the bond angle degree will always remain the same with the VSEPR model that it corresponds with because. For example, has an image of the many compounds that have the same molecular shape that corresponds to a certain degree. I hope that helps. :)
