### 2F.15

Could someone please explain the answer to this homework question? Also, what does it mean by the "s-character" or the hybrid?

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

"As the s-character of a hybrid orbital increases, the bond angle increases"

sp hybridization refers to the mixing of the s and p orbitals. What the answer implies is that decreasing the amount of p orbitals from 3 to 2 increases the bond angle and the answer asserts that increasing the amount of s orbitals for sp hybridization will in contrast increase the bond angle.
