Question

$\textbf{Match List I with List II}$
\begin{array}{|c|c|c|} \hline \text{List I (Spectral Series for Hydrogen)} & \text{List II (Spectral Region/Higher Energy State)} \\\ \hline \text{A. Lyman} & \text{I. Infrared region} \\\ \text{B. Balmer} & \text{II. UV region} \\\ \text{C. Paschen} & \text{III. Infrared region} \\\ \text{D. Pfund} & \text{IV. Visible region} \\\ \hline \end{array}
$\text{Choose the correct answer from the options given below :-}$

• A. A-II, B-III, C-I, D-IV
• B. A-I, B-III, C-II, D-IV
• C. A-II, B-IV, C-III, D-I
• D. A-I, B-II, C-III, D-IV

Answer 1

Answer: (C)

A-II, B-IV, C-III, D-I

Answer 2

The correct matching is as follows:

- A. Lyman series corresponds to the UV region (II) as it involves transitions to the $n=1$ energy level.
- B. Balmer series corresponds to the Visible region (IV) as it involves transitions to the $n=2$ energy level.
- C. Paschen series corresponds to the Infrared region (III) as it involves transitions to the $n=3$ energy level.
- D. Pfund series corresponds to the Infrared region (I) as it involves transitions to the $n=5$ energy level.

The Correct Answer is: $A - II, B - IV, C - III, D - I$
