Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: In Lyman series of H-spectra, the maximum wavelength of lines is 121.65 nm. Reason: Wavelength is maximum if there is transition from the very next level.A) If both Assertion: and Reason: are true and the Reason: is the correct explanation of the Assertion:
B) If both Assertion: and Reason: are true but the Reason: is not the correct explanation of the Assertion:
C) If Assertion: is true but Reason: is false
D) If both Assertion: and Reason: are false
Correct Answer: A
Solution :
\[{{N}^{I}}\] For Lyman series, \[{{N}^{II}}\] and \[{{N}^{II}}\] [\[Electrical\text{ }conductances\propto \frac{1}{size\text{ }of\text{ }hydrated\text{ }cation}\] for maximum K, transition is from very next level.] \[(N{{H}_{3}})=14+3=17\] \[(N{{H}_{3}})=14+14=28\] or \[N{{H}_{3}}\] \[[Ca{{(ClO)}_{2}}],\] \[CaC{{l}_{2}}\]
