Match the List I with List II Choose the correct answer from the options given below: (a) A-III, B-IV, C-I, D-II (b) A-II, B-IV, C-I, D-III (c) A-IV, B-II, C-III, D-I (d) A-III, B-II, C-IV, D-I

Answer: (a). Use γ = 1 + 2/f. (A) Triatomic rigid (non-linear): f = 6, γ = 4/3 → (III). (B) Diatomic non-rigid: f = 7, γ = 9/7 → (IV). (C) Monoatomic: f = 3, γ = 5/3 → (I). (D) Diatomic rigid: f = 5, γ = 7/5 → (II). So the answer is (a) A-III, B-IV, C-I, D-II.

Show answer and solution

Answer: (a)

Use $\gamma = 1 + \frac{2}{f}$ .
(A) Triatomic rigid (non-linear): $f = 6$ , $\gamma = \frac{4}{3}$ $\to$ (III).
(B) Diatomic non-rigid: $f = 7$ , $\gamma = \frac{9}{7}$ $\to$ (IV).
(C) Monoatomic: $f = 3$ , $\gamma = \frac{5}{3}$ $\to$ (I). (D) Diatomic rigid: $f = 5$ , $\gamma = \frac{7}{5}$ $\to$ (II).
So the answer is (a) A-III, B-IV, C-I, D-II.
