Match the LIST-I with LIST-II LIST-I (Classification of molecules based on octet rule) A. Molecules obeying octet rule B. Molecules with incomplete octet C. Molecules with incomplete octet with odd electron D. Molecules with expanded octet LIST-II (Example) I. NO, NO2 II. BCl3, AlCl3 III. H2SO4, PCl5 IV. CCl4, CO2 Choose the correct answer from the options given below :

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

Correct answer: A-IV, B-II, C-I, D-III

Solution

The correct option matches each classification of molecules with appropriate examples: A-IV pairs molecules that fully obey the octet rule (like CCl4 and CO2), B-II includes those with incomplete octets (like BCl3 and AlCl3), C-I lists molecules with odd electrons (like NO and NO2), and D-III consists of molecules with expanded octets (like H2SO4 and PCl5).
