Concept introduction:
The carbon-carbon triple bond of an alkyne undergoes electrophilic addition when treated with a strong Bronsted acid. In the first step, the proton is added to a carbon-carbon triple bond to form a vinylic cation. The conjugate base of the acid then coordinates with the cation. An

Concept introduction:
The oxidation of terminal alkyne is carried out by using bulky dialkylborane like disiamylborane
Sodium borohydride,
The electrophilic addition of molecular bromine across the double bond of an alkene forms a vicinal dibromide. The addition of molecular bromine involves a cyclic bromonium intermediate, either above or below the plane of the double bond, leading to the formation of a racemic mixture of the products.
