JEE MainChemistryBasics of Organic ChemistryMCQ+4 / −1

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. sp2 hybridized carbon with empty p-orbital.
D. Electrophile IV. sp2/sp3 hybridized carbon with one unpaired electron.

Choose the correct answer from the options given below:

  1. A
    A-IV, B-II, C-III, D-I
  2. B
    A-II, B-III, C-I, D-IV
  3. C
    A-III, B-IV, C-I, D-II
  4. D
    A-III, B-IV, C-II, D-I

Correct answer: C

  1. Identify each species/term in LIST-I

    • A. Carbocation: A carbocation is a positively charged carbon species. The carbon is typically sp2sp^2sp2 hybridized and has an empty ppp-orbital.

      So, A →\to→ III.

    • B. C-Free radical: A carbon free radical has one unpaired electron. Such carbon is generally considered sp2sp^2sp2 or sometimes nearly sp3sp^3sp3 hybridized depending on structure.

      So, B →\to→ IV.

    • C. Nucleophile: A nucleophile is an electron-rich species that donates a pair of electrons.

      So, C →\to→ I.

    • D. Electrophile: An electrophile is an electron-deficient species that accepts/receives a pair of electrons.

      So, D →\to→ II.

  2. Write the complete matching

    • Option B: AAA-II, BBB-III, CCC-I, DDD-IV ❌
    • Option C: AAA-III, BBB-IV, CCC-I, DDD-II ✅
    • Option D: AAA-III, BBB-IV, CCC-II, DDD-I ❌
  4. Final answer

    The correct option is C.
