O Markovnikov addition: Alkene will accquire proton using the less substituted C so that it will produce more stable carbocation on the more substituted C. Markovnikov addition: Alkene will accquire proton using the more substituted C so that it will produce more stable carbocation on the more substituted C. anti-Markovnikov addition: Alkene will accquire a halide ion using the less substituted site to avoid larger steric hindrance...
