“Without organic reactions, there wouldn’t be life or much of anything else that is worthwhile”
Simple acid-base reactions
Lewis acid-base reaction
Basic Reaction Types
Basic Bond Cleavages
Will cover in Chapter 10
Bond Formation
Trends in Acidity (pKa)
Trends in Acidity (pKa)
Having more s character means that the electrons of the anion will be closer to the positively charged nucleus and hence lowers the energy (more stable)
Hybridization sp sp2 sp3
% S character 50% 33% 25%
