Problem 4.43

Postby 504594108 » Mon Oct 26, 2015 12:40 pm

What is meant by the s-character of hybrid orbitals? Why does it increase when the bond angle increases?

The S character can be thought of as the influence that the s orbitals exert on the bond

Hi, from what I understand s-character relates to how much of the hybrid orbital is made of the s-orbital
like in sp hybridization, s-character is 50% and p-character is 50%, but in sp^3, s-character is 25% where p-character is 75% of the hybridization.
so as bond angle increases, s-character increases because for example in a 180 degree angle the hybridization is likely to be sp so s-character (50%) is higher than that for a hybridization of sp^3 (s-character is 25%) where the bond angle is 109.5 degrees.
