Basic Bond Cleavages Will cover in Chapter 10
Trends in Acidity (pKa) Hybridization sp sp2 sp3 % S character 50% 33% 25% 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)
Examples of Reactions acid/base HCl heterolytic cleavage nucleophilic attack
