Match List-I with List-II. List-I A. 16 g of CH4(g) B. 1 g of H2(g) C. 1 mole of N2(g) D. 0.5 mol of SO2(g) List-II I. Weighs 28 g II. 60.2 × 10^23 electrons III. Weighs 32 g IV. Occupies 11.4 L volume at STP Choose the correct answer from the options given below:

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

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

Solution

The correct matches are based on the molar masses and properties of the substances: CH4 weighs 16 g per mole and contains 28 g of electrons (A-II), H2 weighs 2 g per mole and occupies 11.4 L at STP (B-IV), N2 weighs 28 g per mole (C-I), and SO2 weighs 64 g per mole, so 0.5 mol weighs 32 g (D-III).
