Question

Match the LIST-I with LIST-II 

Choose the correct answer from the options given below:

• A. A-III, B-III, C-I, D-IV
• B. A-III, B-IV, C-II, D-I
• C. A-IV, B-II, C-III, D-I
• D. A-III, B-IV, C-I, D-II

Hint:

- Carbocation: \(\text{sp}^2\), 6 electrons, planar - Free radical: 7 electrons, can be \(\text{sp}^2\) or \(\text{sp}^3\) - Nucleophile: "nucleus loving" (e\(^-\) donor) - Electrophile: "electron loving" (e\(^-\) acceptor)

Answer 1

The Correct Option is D

To match LIST-I with LIST-II, we need to understand the definitions and characteristics of each term:

1. Carbocation: A carbocation is a species with a positively charged carbon atom. It has an empty p-orbital, making it an electron-deficient species. Hence, a carbocation corresponds to III (sp² hybridized carbon with empty p-orbital).
2. C-Free radical: A carbon free radical has one unpaired electron making it a reactive species. Hence, it corresponds to IV (sp²/sp³ hybridized carbon with one unpaired electron).
3. Nucleophile: A nucleophile is a species that can donate a pair of electrons. Hence, it corresponds to I (Species that can supply a pair of electrons).
4. Electrophile: An electrophile can accept a pair of electrons due to its electron deficiency. Hence, it corresponds to II (Species that can receive a pair of electrons).

Based on the analysis above, the correct matching is:

• A - III
• B - IV
• C - I
• D - II

Therefore, the correct option is A-III, B-IV, C-I, D-II.

Answer 2

Correct Matching:
- A: Carbocation - III (sp² hybridized carbon with empty p-orbital)
- B: C-Free radical - IV (sp²/sp³ hybridized carbon with one unpaired electron)
- C: Nucleophile - I (Species that can supply a pair of electrons)
- D: Electrophile - II (Species that can receive a pair of electrons)

Explanation:
- Carbocations are electron-deficient species with sp² hybridization and empty p-orbital
- Free radicals have one unpaired electron and can be sp² or sp³ hybridized
- Nucleophiles are electron-rich species that donate electron pairs
- Electrophiles are electron-deficient species that accept electron pairs
