Bond angle

Postby Louise Zhuang » Sun Nov 25, 2018 10:32 pm

Do we have to remember the exact bond angle of shapes with lone pairs(e.g. bent) or we just have to say less than the bond angle with the respective shape without lone pairs?

He said we won't have to know exact angles just that they are less than what they would be without lone pairs.

If you know the bond angles for the general shapes, I think that should be enough. I think that he said that knowing the exact angles would require looking them up usually.

Professor Lavelle made it clear that it is far more important to understand shape than to know specific bond angles. The only important concept to know is that when one of the regions of electron density is a lone pair instead of bonded, the other angles will be smaller and the angles around the lone pair will be larger because it is more repulsive.
