What major product is formed when heptyne is treated with Br2 in CCl4?
2 answers:
<u>Answer: </u>
<em>Option A is the Answer. </em>
<u>Explanation:</u>
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.

Answer : The correct option is,
Explanation :
- Oxidation reaction : It is defined as the reaction in which a substance looses its electrons. That means, the loss of electrons takes place.
Or we can say that, oxidation reaction occurs when a reactant losses electrons in the reaction.
- Reduction reaction : It is defined as the reaction in which a substance gains electrons. That means, the gain of electrons takes place.
Or we can say that, reduction reaction occurs when a reactant gains electrons in the reaction.
According to the electrochemical series, most likely to be reduced because
Hence, the ion most likely to be reduced is .
