Markovnikav addition: The negative part of the reagent is added
to the double bonded carbon atom which is attached to less number
of hydrogen atoms.
Example: Addition of HX, H2O, oxymercuration-demercuration
Anti-Markovnikov addition: the negative part of the reagent is
added to the double bonded carbon atom which is attached more
number of hydrogen atoms.
Example of addition of HX in the presence of light or Peroxide,
Hydroboration-oxidation.
Here reactions a,b, and d are Markovnikav addition
Reactions c,e and f are Antimarkovnikov addition.
