NEET Chemistry Alkenes Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Electrophilic addition | (i) Addition of hydrogen halides to alkenes |
| (b) Markovnikov's rule | (ii) Formation of vicinal glycols |
| (c) Bond enthalpy of C=C | (iii) Stability comparison with alkanes |
| (d) Unsaturation test | (iv) Decolorization of bromine solution |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
Electrophilic addition refers to the reaction mechanism when alkenes react with electrophiles, such as hydrogen halides. Markovnikov's rule applies to the addition of hydrogen halides to alkenes, dictating the formation of more stable products. The bond enthalpy of the C=C double bond is indeed greater than that of single bonds in alkanes, indicating relative stability. The unsaturation test involves the decolorization of bromine solution, confirming the presence of double bonds.
