NEET Chemistry Alkynes Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Addition of H2 | (i) Produces gem dihalides |
| (b) Addition of halogens | (ii) Reaction with unsymmetrical alkynes |
| (c) Markovnikov's rule | (iii) Electrophilic addition reactions |
| (d) Hydrogen halides | (iv) Test for unsaturation |
a-iii, b-iv, c-ii, d-i
a-ii, b-iii, c-i, d-iv
a-iv, b-i, c-iii, d-ii
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
The addition of H2 to alkynes is an example of electrophilic addition reactions (a-iii), while the addition of halogens tests for unsaturation (b-iv). Markovnikov's rule applies to reactions with unsymmetrical alkynes (c-ii), and hydrogen halides react to form gem dihalides (d-i).
