What major product is formed when heptyne is treated with br2 in ccl4?
select one:
a. e-1,2-dibromoheptene
b. 1,1-dibromoheptene
c. z-1,2-dibromoheptene
d. 2,2-dibromoheptene

Option A is the Answer.

Explanation:

Treatment of alkyne with Bromine in the presence of produces a trans product that is, a alkenyl bromide.

E-1, 2-dibromoheptene

It is a trans intermediate on further halogenations produces a tetrabromopentane.  

It is an electrophilic expansion response in which the triple bond breaks to turn into a twofold bond and creates a dibromoalkene (E-1,2 dibromoheptene), and on further expansion, the twofold bond turns into a solitary bond and delivers a tetrabromoalkane.
