Which of the following electronic transition in hydrogen atom will emit largest amount of energy?

Options

A. From n = 2 to n = 1
B. From n = 3 to n = 2
C. From `n=oo" to "n=1`
D. From n = 5 to n = 3

Answer

C

Explanation

`DeltaE=13.6[(1)/((n_(1))^(2))-(1)/((n_(2))^(2))]eV," "DeltaE" is maximum when "n_(2)rarroo and n_(1)=1.`
