Hydrocarbons - Result Question 62
Passage
Schemes $1$ and $2$ describe sequential transformation of alkynes M and N. Consider only the major products formed in each step for both schemes.
47. The product $X$ is

Answer:
Correct Answer: 47. (a)
Solution:
- PLAN: This problem can be solved by using the concept of nucleophilic substitution reaction, oxidation reaction and reduction reaction including strength of nucleophile and regioselectivity.
Reaction of Scheme 1 can be completed as

Among two naked nucleophilic group I and II, II is more nucleophilic and then will react selectively as follows

Hence, using the concept of regioselectivity, we come to the conclusion that the final product is correctly represented by structure (a).
