1.Syn Addition Reaction.
Syn addition occurs when H2 reacts with a double
bond. In this type of a reaction, both hydrogen
atoms are added to the same side 2.The Markovnikov's
rule states that when to an unsymmetrical alkene a reagent
is added then the negative part of the addendum (adding molecule)
gets attached to that carbon atom which possesses lesser number of
hydrogen atoms.
3.Anti-Markovnikov addition: In
an addition reaction of a generic electrophile H2O to an
alkene or alkyne, the hydrogen atom of H2O becomes
bonded to the carbon atom that had the least number of hydrogen
atoms in the starting alkene
