(a)
Interpretation:
The intermediate in first step of given halogenation reaction has to be drawn.
Concept Introduction:
Halogenation of
Intermediate: It is a molecular entity formed from the reactants and then reacts further to give the products.
Alkynes react with excess of halogens in presence of carbon tetrachloride to form tetrahalo-substituted compound.
(b)
Interpretation:
During the second step of halogenation mechanism, a high energy carbocation is formed which has to be drawn and explained.
Concept Introduction:
Halogenation of Alkynes:
Alkynes react with excess of halogens in presence of carbon tetrachloride to form tetrahalo-substituted compound.
(c)
Interpretation:
The reaction mechanism of halogenation with both steps has to be given.
Concept Introduction:
Halogenation of Alkynes:
Alkynes react with excess of halogens in presence of carbon tetrachloride to form tetrahalo-substituted compound.
Mechanism of the reaction is the step-by-step description of the process by which reactants are changed into products.
Curved arrows show the bonds that are formed and the bonds that are broken in a reaction.
