Twin: The Addition Reaction
Captions available
The idea
An addition reaction breaks a double or triple bond's pi component and forms two new single bonds, one to each carbon, changing their hybridization.
In practice
Bromine adds across ethene's double bond, converting the sp2 carbons to sp3 and yielding 1,2-dibromoethane.
Where people slip
Addition happens at an existing multiple bond and changes carbon hybridization — confusing it with the mechanism named next is this twin's target.
