NEET (UG) 2024 — Question 27

Match List I with List II.

	List I (Spectral Lines of Hydrogen for transitions from)		List II(Wavelengths (nm))
A.	${{n}_{2}}=3$ to ${{n}_{1}}=2$	I.	410.2
B.	${{n}_{2}}=4$ to ${{n}_{1}}=2$	II.	434.1
C.	${{n}_{2}}=5$ to ${{n}_{1}}=2$	III.	656.3
D.	${{n}_{2}}=6$ to ${{n}_{1}}=2$	IV.	486.1

Choose the correct answer from the options given below:

Energy difference $\Delta E=\frac{h c}{\lambda}$

$\therefore \lambda \propto \frac{1}{\Delta E}$

$(\Delta E)_{6-2}>(\Delta E)_{5-2}>(\Delta E)_{4-2}>(\Delta E)_{3-2}$

$\lambda_{6-2}<\lambda_{5-2}<\lambda_{4-2}<\lambda_{3-2}$

$\text { A-III, B-IV, C-II, D-I }$
