Definition of Ka
The acid dissociation constant, Ka, is a quantitive measure of the strength of an acid in solution
Definition of pKa
pKa is a property of a given compound that tells us how acidic it is. The lower the pKa the stronger the acid
Defintion of pKaH
pKaH is a measure of acidicity for the conjugate acid of a given base. For example, the protonated version of a base (NH3 -> NH4+)
If pKaH is high it means it is a strong base
What is the Burgi Dunitz Angle
The Burgi Dunitz angle is 107 degrees.
1) GOOD: There is max orbital overlap of Nu HOMO with the LUMO.
2) BAD: There is repulsion between Nu and C=O bonding.
The angle is a compromise between the two.
