Which of the following electronic transitions in hydrogen atom will require the highest energy?

Options

  1. An =4 to n =5
  2. Bn =1 to n =2
  3. Cn =3 to n =5
  4. Dn =2 to n =3

Correct answer

B. n =1 to n =2

Step-by-step solution

A transition from ground state or a state that has the electron closest to the nucleus, will require the highest amount of energy. Thus, n =1 n =2 requires the highest energy.
