Q. Match the LIST-I with LIST-II [table] LIST-I (Classification of molecules based on octet rule) | LIST-II (Example) ; A. Molecules obeying octet rule | I. NO, NO₂ ; B. Molecules with incomplete octet | II. BCl₃, AlCl₃ ; C. Molecules with incomplete octet with odd electron | III. H₂SO₄, PCl₅ ; D. Molecules with expanded octet | IV. CCl₄, CO₂ [/table] Choose the correct answer from the options given below:
A) A-IV, B-I, C-III, D-II
B) A-IV, B-II, C-I, D-III
C) A-II, B-IV, C-III, D-I
D) A-III, B-II, C-I, D-IV
Explanation
[Solution by Dr. Abubacker] CCl₄ and CO₂ obey the octet rule (A–IV). BCl₃ and AlCl₃ have an incomplete octet (B–II). NO and NO₂ have an odd number of electrons (C–I). H₂SO₄ and PCl₅ have an expanded octet (D–III). Answer (2).
