What does a mechanism do

Breaks down a reaction into individual stages. It shows have molecules react together by using curly arrows to show which bonds are made or broken.


What are mechanisms

They are diagrams that break reactions down into individual stages.


What does the curly arrows show

How electron pairs move around.


What needs to happen to break or make a bond

Electrons have to move around


Explain the arrow in mechanism

The arrow starts at the one or lone pair where electrons are at the beginning of the reaction.

The arrow points to where the new bond is formed at the end of the reaction.
