4.43

Postby Emily 1E » Wed Jun 06, 2018 5:51 pm

The question is: Noting that the bond angle of an sp3 hybridized atom is 109.5 and that of an sp2 hybridized atom is 120, do you expect the bond angle between two hybrid orbitals to increase or decrease as the s-character of the hybrids is increased?

What exactly does this mean? What is the s-character of a hybrid? And what is the answer to this question?

They way I thought through this question was that sp3 has bond angles of 109.5, sp2 has 120. Between those two, the p decreased, and the bond angle increased. If we look at sp, its 180. The S character is the s orbital level, so as it increases, the bond angle also increases.
