According to molecular orbital theory, which of the following will not be a viable molecule ?

(a) No  Examples : (i) Cereals / rice / wheat - pollen grains / loose viability with in thirty minutes of their release  (ii) In some members of Rosaceae / leguminoseae / Solanacease...

(c) :- According to the kinetic theory of gases, gas molecules are always in rapid random motion colliding with each other and with the wall of the container and between...

Electron density in s-orbital is equal in all direction while it dumble shaped along one axis in p- orbitals.

No, the energy depends upon (n+l) values in an atom. Hence 2p orbital has greater energy than 2s.

Because s orbital has same electron distribution in all axis/ directions.

(i)The bonding molecular orbital has lower energy and hence greater stability than the corresponding antibonding molecular orbital.  (ii) Just as the electron probability distribution around a nucleus in an atom is...

sp because lobes of p orbital have equal electron density whereas sp hybrid orbital has greater electron density on one side

It is formed by the combination of two hydrogen atoms. Each hydrogen atom has one electron in 1s orbital. Therefore, in all, there are two electrons in hydrogen molecule which...

An atomic orbital is monocentric while a molecular orbital is polycentric.

Helium molecule (He2 ): The electronic configuration of helium atom is 1s2. Each helium atom contains 2 electrons, therefore, in He2 molecule there would be 4 electrons. These electrons will...
