E = opposite sides
What is a constitutional isomer?
Different nature/sequence of bonds
What is a conformational isomer?
Differ by rotation
What is a configurational isomer?

What does a curly arrow indicate?
Electron pair movement.
Where does a curly arrow begin?
At a negative sign - or at the electron pair that moves.
What does a curly arrow from a bond indicate?
The breaking of that bond.
What does a curly arrow between two species indicate?
The formation of a bond.
