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,http://images.tutorcircle.com/cms/images/44/vsepr-model-chart.png has an image of the many compounds that have the same molecular shape that corresponds to a certain degree. I hope that helps. :)
