Linear Combination Of Atomic Orbitals

According to the moleular orbital theory, all atomic orbitals combine to form molecular orbital by LCAO (linear combination of atomic orbitals) method When two atomic orbitals have additive (constructive) method When two atomic orbitals have additive (constructive) overlapping they form bonding molecular orbitals (BMO) which have lower energy than atomic orbitals whereas when atomic orbitals overlap subtractive higher energy antibonding molecular orbitals (ABMO) are formed Each MO occupies two electrons with opposite spin Distribution of electrons in MO follows Aufbau principle as well as Hund's rule MO theory can successfully explain the magnetic behaviour of molecules O_(2)^(2-) will have .

The concept of hybridisation has been introduced to explain the shapes of molecules. It involves the intermixing of two or more atomic orbitals belonging to same atom but in or more atomic orbitals beloging to sasme atom but in different sub-shells so as to intermix and redistibute energies to from equivalent orbitals called hybrid orbitals.Depending upon toh enumber and nature of the orbitals involved, the hybridisation may be divided into sp (linear), sp^(2) (trigonal), sp^(3) (tetrahedral), sp^(3)d (trigonal bipyramidal), sp^(3)d^(3) (octahedral) and sp^(3)d^(3) (pentagonal bipyramidal) types. it may be noted that the orbitals of isolated atoms never hybridise and they do so at the time of bond formation. The d-orbital involved in dsp^(2) hybridisation is:

According to MOT, two atomic orbitals overlap resulting in the formation of molecular orbital formed. Number of atomic orbitals overlapping together is equal to the molecule orbital formed. The two atomic orbital thus formed by LCAO (linear combination of atomic orbital) in the phase or in the different phase are known as bonding and antibonding molecular orbitals respectively. The energy of bonding molecular orbital is lower than that of the pure atomic orbitals by an amount Delta . This known as the stabilization energy. The enerby of antibonding molecular orbital in increased by Delta' (destabilisation energy). Q. which of the following combination of orbitals is corrects?
