2F. 15 What does it mean for S-character to increase?

[Samantha Low 3D]

For number 2F.15, what does it mean when it talks about the s character of hybrids? Is S-character quantifiable? For example, would sp be 50% s and 50% p and sp² be 33% s-character and 66% p-character? Or is it more of a generalization to describe hybrids?

Yes, the s-character is quantified just as you explained it. In terms of question 2F.15, it means that bond angle will increase as s-character increases, as an sp2 orbital has 33% s-character, while an sp3 orbital has 25% s-character.

Thank you for your help! I don't remember learning about this in lecture, is it in the textbook?

I found another Chemistry Community post and a chemistry website about it

I couldn't find anything about quantifying s-character in the textbook

I understand the quantification, but what does s-character actually mean? How does this relate to molecular shape?
