Bond Angles

Postby altaing » Sun Nov 26, 2017 10:29 pm

Will we need to know the exact bond angles for each molecule or compound?

I don't think Lavelle expects us to know how to calculate or remember the bond angles, but try to at least remember how to work out every AXE formation. Also keep in mind that lone pairs, E, will repel electron densities more, which will make their bond angles lesser than usual since they are getting pushed together.

I don't believe it is required but it is pretty helpful to know them for each of the arrangements

I believe that with this unit in general, Dr.Lavelle emphasized that we should come to understand each of the molecular structures. Knowing the arrangements and shapes will allow us to draw conclusions about bond angles and how they are affected by lone pairs. I think it might be better if we understand the concepts between the influence of bonding regions and etc on shape and angles as oppose to memorize details.

Do you know if Dr. Lavelle has a chart of all the shapes and bond angles of the different shapes? Also, some angles are a bit confusing, as some may say approximately less than 109, whereas a solution may be more accurate, such as 107.5. Should we know the exact numbers?
