The energy of second Bohr orbit of the hydrogen atom is `- 328 k J mol^-1`, hence the energy of fourth Bohr orbit would be.

Options

A. `-41" k J mol"^(-1)`
B. `-1321" k J mol"^(-1)`
C. `-164" k J mol"^(-1)`
D. `-82" k J mol"^(-1)`

Answer

D

Explanation

`(E_(4))/(E_(2))=(2^(2))/(4^(2))=(1)/(4)" "rArr" "E_(4)=-82kJ//mol`
