Interpretation: The product that is formed by the reaction is to be drawn.
Concept introduction: The addition of an electrophile to an alkyne is followed by Markovnikoff’s rule and anti-stereoselectivity.
The addition of a halogen to an alkyne chain leads to the formation of corresponding alkene or alkane. The reaction which includes the addition of bromine atoms to the alkyne chain is known as bromination. Bromination can be done by using the reagents like
