1.The energy of second Bohr orbit of the hydrogen atom is −328 kJ mol−1-328\ kJ\ mol^{-1}−328 kJ mol−1; hence the energy of fourth Bohr orbit would bea.−41 kJ mol−1-41\ kJ\ mol^{-1}−41 kJ mol−1b.−82 kJ mol−1-82\ kJ\ mol^{-1}−82 kJ mol−1c.−164 kJ mol−1-164\ kJ\ mol^{-1}−164 kJ mol−1d.−1312 kJ mol−1-1312\ kJ\ mol^{-1}−1312 kJ mol−1Login to continueOnly logged in users canattempt or see the solution.
