S Character

Postby 005388369 » Thu Dec 05, 2019 9:58 am

In one of the homework problems, there is a question asking if a bond angle would increase or decrease as the S character of a hybrid orbital increases? What does the "s character" mean? Can someone explain this please? Thank you

S character refers to the contribution of the s-orbital in hybridization. For example in a sp2 notation, there would be 33% s character and 66% p character. In a sp3 notation, there would be 25% s character and 75% p character.

More s-character means that the shape of the orbital would be more similar to the shape of a normal s-orbital.

so the s-character is a ratio of s orbitals to the other hybridized orbitals?

Yes, it's typically written as a percentage!
