Summary
Alkenes contain the unsaturated C=C functional group which characteristically
undergo addition reactions.
This is driven by the conversion of the weaker p
bond
into 2 new, stronger s bonds.
The reactions of alkenes can seem a little bewildering as a wide variety
of reagents undergo this type of reaction providing access to products
with various regioselectivities and stereoselectivities depending on the
reagent and / or reaction conditions, but ultimately on the mechanism by
which the reaction occurs.
There are potentially 3 factors associated with each of the addition reactions of alkenes:
