Type 16 Lewis Acid/Base Complexation Chemistry
Electrophilic Addition and SEAr Reactivity

Bonding:	Halogen/alkene Type 16 complexes exhibit extensive back-bonding.
Charge:	Positively charged complex, such as the bromonium ion, or some reaction pathway may yield products with a variety of charges.
Chemistry:	Classical Organic Chemistry Many vacant p orbital Lobe-LUMO Lewis acids, particularly carbenium ions and acylium ions, are aggressive electrophiles, E⁺, able to react with π-HOMO organics, such as alkenes, via electrophilic addition or electrophilic addition-followed-by-elimination. For example: An electrophile, E⁺, may react with benzene and other aromatics to give (Friedel-Crafts or nitration) electrophilic aromatic substitution products:
Congeneric Series:	Few congeneric series or planars of interest.
