In this markoniv addition takes place.

Markoniv addition=Positive ion will go to that double bonded carbon which has more no of hydrogens attached and negative ion will go towards that carbon which has less number of hydrogens attached.

Ozonolysis= During ozonolysis the double bond will break and oxygen make a double bond with carbon and form two products.

Reduction= Addition of H₂ on the both double bonded carbons to form a single bond.

Hydroboration-oxidation= In this anti markoniv addition takes place.

Here markoniv addition takes place.So Br^- attached with that carbon which has less number of hydrogen atoms and H⁺ attached with that carbon which has more number of hydrogen atoms.

When peroxyacid react with an alkene then it breaks a double bond and both the double bonded carbon atoms make bond with single oxygen and epoxide formation takes place.

Here ozonolysis takes place. During ozonolysis the double bond will break and oxygen make a double bond with carbon.

Here Br⁺ will form from Br₂and OH^- will form from H₂O and markoniv addition takes place and HBr releases.

Here markoniv addition takes place. So OCH₃^- attached with that carbon which has less number of hydrogen atoms and H⁺ attached with that carbon which has more number of hydrogen atoms.

Here markoniv addition takes place. So OH^- attached with that carbon which has less number of hydrogen atoms and H⁺ attached with that carbon which has more number of hydrogen atoms.

In Hydroboration-oxidation anti markoniv addition takes place.

Here Br₂ dissociate as Br^- and Br⁺ and markoniv addition takes place.
