The ionisation energy of H atom is x kJ. The energy required for the electron to jump from n=2 to n=3 will be

A

5x

B

36x/f

C

5x/36

D

9x/4

Text Solution

Verified by Experts

The correct Answer is:
C

I.E. `=E_(oo)-E_(1)`
`=0-(-1311.8/1)=1311.8=x`
Energy required `=-1311.8/(3^(2))-(-1311.8/(2^(2)))`
`-x/9+x/4` or `(5x)/36`.
