Elimination
( \newcommand{\kernel}{\mathrm{null}\,}\)
An elimination is a reaction in which an organic compound loses two ligands without gaining any.
eg. 1:
net reaction:
In this reaction, 1 loses two ligands, H and Br, without gaining any. Therefore, this reaction is an elimination reaction.
eg. 2:
net reaction:
In this reaction, 2 loses two ligands, H and Cl, without gaining any. Therefore, this reaction is an elimination reaction.
Overall, elimination is the exact opposite of addition.
