| List-I | List-II |
|---|---|
| (A) Lyman | (i) n = 2, 3, 4, ... |
| (B) Balmer | (ii) n = 3, 4, 5, ... |
| (C) Paschen | (iii) n = 4, 5, 6, ... |
| (D) Bracket | (iv) n = 5, 6, 7, ... |
Hydrogen spectral series and their transitions:
• Lyman series ends at n=1 and involves levels of n=2,3,4 etc.
• Balmer series ends at n=2 and involves energy levels of n=3,4,5 etc
• Paschen series ends at n=3 and involves energy levels of n =4,5,6 etc
• Bracket series ends at n=4 and involves energy levels of n=5,6,7 etc
The correct matching is: (A) - (i), (B) - (ii), (C) - (iii), (D) - (iv).
