Which of the following statements is not correct regarding bonding molecular orbitals?
1 Bonding molecular orbitals possess less energy than the atomic orbitals from which they are formed.
2 Bonding molecular orbitals have low electron density between the two nuclei.
3 Electron in bonding molecular contibutes to the attraction between atoms.
4 They are formed when the lobes of the combining atomic orbitals have the same sign.
Explanation:
Bonding M.O. has maximum electron density between two nuclei.

The number of nodal planes present in \({{\rm{\sigma }}^{\rm{*}}}{\rm{s}}\) anti bonding orbitals is
1 0
2 3
3 1
4 2
Explanation:
The molecular orbital \({{\rm{\sigma }}^{\rm{*}}}{\rm{s}}\) formed by the subtraction of overlapping of two s-orbitals. atoms and thus six \(\pi \,{\rm{ - }}\) electrons are delocalized.

Main axis of diatomic molecule is z. The orbitals \({{\rm{p}}_{\rm{x}}}\,\,{\rm{and}}\,\,{{\rm{p}}_{\rm{y}}}\) overlap to form.
1 \({\rm{\pi }}\,{\rm{ - }}\) molecular orbital
2 \({\rm{\sigma }}\,{\rm{ - }}\) molecular orbital
3 \({\rm{\delta }}\,{\rm{ - }}\) molecular orbital
4 no bond is formed
Explanation:
The \({{\rm{p}}_{\rm{x}}}\,\,{\rm{and}}\,\,{{\rm{p}}_{\rm{y}}}\) orbitals do not overlap thus, no bond is formed, because of different symmetry or direction of axes.
