Test 3 Material Flashcards
Atom that becomes a chiral center by changing 1 substituent.
Prochiral
A prochiral substituent that when changed creates an R oriented chiral center
Pro-R
A prochiral substituent that when changed creates an S oriented chiral center
Pro-S
A type of reaction that happens when two or more reactants result in one product.
Addition reaction
A type of reaction that occurs when 1 reactant split to form two or more products.
Elimination reaction
A type of reaction that occurs when multiple reactants exchange parts to form new multiple products.
Substitution reaction
The overall description of how the reaction occurs. All reactants and products, broken and formed bonds, order, relative rates for each step.
Mechanism
A type of bond break that results in homolytic bond cleavage and 1 electron per fragment.
Radical bond fra
Type of bond break that results in heterolytic cleavage and the electron pair remaining intact
Polar bond formation and fracture
A neutral species with an odd number of electrons
Radical
A radical reaction in which a radical takes the place of another atom or group in a bigger molecule, resulting in a new radical
Radical substitution
A radical reaction in which a radical attaches to a bigger molecule but doesn’t force off another piece.
Radical addition
The three steps of radical mechanism
Initiation, propagation, termination
Homolytic cleavage to cause radicals to form single bonds
Initiation
the chain reaction of radical mechanism which results in/is many radical substitutions occurring one after another.
Propagation
