Mechanism of Reaction Flashcards
Define the mechanism of a reaction.
The mechanism of a reaction is the detailed step-by-step description of how the overall reaction occurs
What are reaction mechanism?
They are theories put forward in order to explain how a particular reaction occurs
Why might reaction mechanisms have to be modified?
They may have to be in the light of new facts discovered about a particular reaction
In relation to bonds, what occurs during a chemical reaction?
Bonds are broken and new bonds are formed
What always happens during a chemical reaction when bonds are broken or formed?
There is a rearrangement of electrons
How do chemists show the rearrangement of electrons?
They use curly arrows
What exactly is a curly arrow used for?
They are used to show electron movement from the tail to the head of the arrow
How is the movement of two electrons shown?
It is shown using a double-headed curly arrow
