Organic

AQA Content

write balanced equations for the steps in a free-radical mechanism.
outline mechanisms by drawing the structures of the species involved and curly arrows to represent the movement of electron pairs.

Specification Notes

Reactions of organic compounds can be explained using mechanisms.
Free-radical mechanisms:
the unpaired electron in a radical is represented by a dot
the use of curly arrows is not required for radical mechanisms.

Other mechanisms:
the formation of a covalent bond is shown by a curly arrow that starts from a lone electron pair or from another covalent bond
the breaking of a covalent bond is shown by a curly arrow starting from the bond.
