Q

What is the Regiochemistry & stereochemsitry of Hydrohalogenation reaction?

A
  1. Regiochemsitry: Markovnikov addition (Adds HX) but its an Anti-Markovnikov addition if ROOR is present
  2. Stereochemistry: Unknown when one or two chirality center formed then both pairs of enantiomers obersved in a racemic mixture
