occur when two reactants ADD TOGETHER to form a single new product with no atoms “left over.”
ADDITION REACTION
A + B → AB
ADDITION RXN
occur when two reactants EXCHANGE PARTS to give two new products.
SUBSTITUION REACTIONS
AB + C → CB + A
SUBSTITUTION RXN
occur when a single reactant undergoes a REPRGANIZATION of bonds and atoms to yield a single isomeric product.
