Question

Match List - I with List - II. 

• A. (a)-(iv), (b)-(ii), (c)-(iii), (d)-(i)
• B. (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
• C. (a)-(i), (b)-(iv), (c)-(ii), (d)-(iii)
• D. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Hint:

Use the color wheel: Blue/Violet has the highest energy (shortest $\lambda$), and Red has the lowest energy (longest $\lambda$).

Answer 1

The Correct Option is B

Step 1: LiCl (Crimson Red): Long wavelength $\approx 670.8 \text{ nm}$.
Step 2: NaCl (Golden Yellow): Characteristic doublet $\approx 589.2 \text{ nm}$.
Step 3: RbCl (Red-Violet): Wavelength $\approx 780.0 \text{ nm}$ (Near IR/Deep Red).
Step 4: CsCl (Blue): Shortest wavelength $\approx 455.5 \text{ nm}$.
