Answer 2

$\large\bold\red{Addition\: Reactions}$

• In Addition Reactions, like hydrogenation, a hydrogen atom is added to each end of a double or triple bond.

• Addition Reactions include addition of hydrogen halides, sulfuric acid, water ( in the presence of an acid catalyst), and halogens, etc.

• Addition Reactions can be done with alkenes as well as alkynes.

• An Addition Reaction results in the conversion of one pi - bond and one sigma- bond into two sigma- bonds.

• The addition Reactions usually results in the stability of the compound which makes it energetically favourable.

• The energy released in making two sigma - bonds exceeds that needed to break one sigma- bond and one pi- bond.

• Therefore, Addition Reaction is usually exothermic.
