An electron undergoes a transition from n = 2 to n = 5.According to Bohr's model,the change in angular momentum of the electron is
E)None of these is correct.

In Bohr's model, the angular momentum of an electron is given by L = nh/2π, where n is the principal quantum number, h is Planck's constant, and π is the mathematical constant pi. Therefore, the change in angular momentum can be calculated using ΔL = Lfinal - Linitial = (5h/2π) - (2h/2π) = (3h/2π) = 11.79 x 10^-34 J•s. Rounded to two significant figures, the answer is 1.2 x 10^-34 J•s, which matches choice B.
