Write the important conditions required for the linear combination of atomic orbitals to form molecular orbitals.
Write the important conditions required for the linear combination of atomic orbitals to form molecular orbitals.
The given conditions should be satisfied by atomic orbitals to form molecular orbitals:
$(a)$ The combining atomic orbitals must have the same or nearly the same energy. This means that in a homonuclear molecule, the $1 s$ - atomic orbital of an atom can combine with the $1s$ - atomic orbital of another atom, and not with the $2 s$ - orbital.
$(b)$ The combining atomic orbitals must have proper orientations to ensure that the overlap is maximum.
$(c)$ The extent of overlapping should be large.
