a level chemistry aqa mechanism questions

What are the curly arrows in a level chemistry?
Curly arrows are used to show how the mechanism proceeds.
Quite simply, they represent the movement of a pair of electrons in the breaking or forming of a covalent bond.
If a covalent bond is breaking, the curly arrow will originate at that bond and this should be clearly shown in your mechanism.
How are organic mechanisms classified?
What are the types of reaction mechanisms in organic chemistry? There are six main types of reaction mechanisms in organic chemistry.
These include substitution, addition, elimination, rearrangement, radical, and re-dox reactions.
Organic Chemistry – Organic chemistry is the study of carbon compounds that always contain carbon and it is limited to other elements.
Compounds obtained from plants and animals were termed organic to indicate their ultimate source was a living organism.

What are the mechanisms in a level chemistry?
