An ionized H-molecule consists of an electron and two protons. The protons are separated by a small distance of the order of angstrom. In the ground state,
A. the electron would not move in circular orbits.

B. the energy would be (2)4 times that of a H-atom.

C. the electrons, orbit would go around the protons.

D. the molecule will soon decay in a proton and a H-atom.

Answer :

In H-molecule two nucleus of 2 H-atoms are separated by the order of angstrom, which means nuclear forces will exist and hence electron wouldn’t move in circular orbits. So option (a) is correct. Now in ground state energy of H-atom will be in accordance with Bohr calculation so option (b) is wrong, now we know one electron and two protons are there so electron will revolve around protons so option (c) is correct and obviously (d) option is wrong.

Therefore option (a) & (c) are correct.
