a covalent bond that breaks and both electrons of the bond go with one atom and the other atom is left with none
a covalent bond that breaks and each atom in the bond gets one electron from the bond breaking
step in a radical reaction where a covalent bond breaks and produces two radical species
functional group that is able to leave a compound and usually forms a stable (weak) species
step in a reaction mechanism. The four mechanistic steps are proton transfer, nucleophilic attack, loss of a leaving group, and rearrangement.
molecule or ion rich in electrons that donates a pair of electrons that forms a covalent bond
step in a radical chain reaction where a reactive free radical reacts with a stable molecule to form a new free radical
step in a radical reaction where two radicals combine to form a covalent bond and no new radicals are formed
