When two `AO` s combine energy of bonding `MO` is lowered by x while of antibonding `MO` is raised by y Then .

The electrons in atoms occupy atomic orbitals (AO_(s)) that are represented as theregions around the nuclei where there is a high probability of finding the electrons. ln the so-called LCAO (linear combitaks) approach, as pioneered by Hund and Mulliken, when AOs come close together, they overlap forming MOs (molecular orbitals). Two AO s can overlap to form two MOs, one of which lies at a lower energy level (BMO) than the other at a higher energy level and is called an antibonding molecular orbital (ABMO). Each MO can hold one or two electrons in accordance with Pauli's exclusion principle. MOT can explain the paramagnetism of molecules such as O_(2) and NO and other spectral features. In a molecule number of electrons in bonding MO is more as compared to antibonding MO, hence

Out of bonding and antibonding M.O, which is filled first and why?

Out of bonding and antibonding M.O, which is filled first and why?

When two A.O. combine they form B.MO & ABMO. During BMO .x. energy is released & during ABMO .y. energy is absorbed. So the correct relation will be :-

Molecular orbitals are formed by the overlap of atomic orbitals. Two atomic orbitals combine to form two molecular orbitals called bonding and antibonding MO s . The molecular orbitals are filled with electrons following the same rules as followed for filling of atomic orbitals. The molecular orbitals electronic configurations help us to calculate bond order when which give important information about bond strength and bond length. Considering Z - axis as internuclear axis, which one of the following will be for sigma antibonding MO? (i) 2p_(y)+2p_(y)" "2p_(x)-2p_(y) (iii) 2s+2p_(z)" "(iv) 2p_(z)-2p_(z)
