JEE Main 2025 Apr 8 Shift 2, Chemistry Q2: Introduction to Mechanism of Organic Reaction
JEE Main2025Apr 8, Shift 2Chemistry
Q.
Match the LIST-I with LIST-II
| LIST-I | LIST-II |
|---|---|
| A. Carbocation | I. Species that can supply a pair of electrons. |
| B. C-Free radical | II. Species that can receive a pair of electrons. |
| C. Nucleophile | III. sp hybridized carbon with empty p-orbital. |
| D. Electrophile | IV. sp/sp hybridized carbon with one unpaired electron. |
Choose the correct answer from the options given below:
- A
A-IV, B-II, C-III, D-I
- B
A-II, B-III, C-I, D-IV
- C
A-III, B-IV, C-II, D-I
- D
A-III, B-IV, C-I, D-II
Solution
A carbocation carries an empty p-orbital on an sp hybridised carbon, so A matches III.
A carbon free radical has one unpaired electron on an sp/sp hybridised carbon, so B matches IV.
A nucleophile is, by definition, a species that donates an electron pair, so C matches I.
An electrophile is a species that accepts an electron pair, so D matches II.
Combining these gives A-III, B-IV, C-I, D-II, which is option (4).
