Homework hybrid orbitals

Postby sarahtang4B » Tue Nov 27, 2018 1:31 pm

For homework question 2.F.15 it asks: noting that the bond angle of an sp3 hybridized atom is 109.5 and that of an sp2 hybridized Atom is 129 do you expect bond angle between two hybrid orbitals to increase or decrease as s-character of the hybrids is increased. What is the s-character and how do we do this problem?

The s character is the proportion of the hybridized orbital that is s. A hybridized orbital is like an average of the types of orbitals that make it up, so an sp2 hybridized orbital has less s character than an sp orbital. As the s-character increases, the angle also increases. Hope this helps!
