Drawing the Transition State

[Nathan Sanchez 1F]

How do you know what the Transition State for the steps of the electrophilic addition reactions look like? Are there any common characteristics between the transition states of all electrophilic addition reactions?

[Jenny2G]

Transition states are when there are the dashed lines indicating broken or formed bonds. They are the middle state between reactants and products. So if the slow step is the first step the graph will have a higher hump on the first transition step.

[Vincent Tse 2B]

Using the reaction's name itself, the first step usually consists of the electrophile forming a bond to the electron source and the bond between the electrophile and its former group being broken; usually 2 bonds being broken in the first step, and, thus, why it is also the slow step.
