Noting that the bond angle of an sp 3 hybridized atom is 109.5 8 and that of an sp 2 hybridized atom is 120 8 , do you expect the bond angle between two hybrid orbitals to increase or decrease as the s-character of the hybrids is increased?
I am confused on what it means for an s-character to increase. The solution says that the bond angle will increase but i am confused why.

I believe by saying the S character increases, the s orbital is becoming prominent. So sp (one has 2 hybridized orbitals, one s and one p) has a larger bond angle than sp2 (which has 3 hybridized orbitals, 1 s and 2 p). etc. Hope this helps!

Bond angle increases with more s character... Sp2 has more than Sp3 etc

Generally, the bond angle increases, s-character increase in the hybrid bond with a proportional relationship. The more s-character of hybrid orbital a molecule has, the greater the angle between the bond.
