The wave function of a molecular orbital formed by reinforce of wave functions of Psi_(A) and Psi_(B) of atomic orbital A and B is represented as

A particle of mass m is attached to a spring of spring constant .k. and has a natural frequency omega_(0) . An external force F(t) proportional to cos omega t(omega != omega_(0)) is applied to the oscillator. The maximum displacement of the oscillator will be proportional to

The total wave function Psi may be symmetric (denoted by subscript S) or anti symmetric (denoted by the subscript A) depending on the symmtry of the function Psi and S. The function Psi = Psi_(S)S_(S) and Psi_(S) = Psi_(A)S_(A) are obviously symmetric whereas the function Psi_(A) = Psi_(A)S_(A) and Psi_(A) = Psi_(A)S_(S) are antisymmtric. All the functions Psi_(S) and Psi_(A) however do not corresponds to the state of an atom are governed by the Pauli principle. Pauli principle is regulated as one of the general principles underlying the modern quantum statistics. Now if two electron are supposed to have identical quantum numbers then transposition of these electrons will yield a state identical with the initial state and consequantly Psi_(12) = Psi_(21) (for symmetric) and Psi_(12) = - Psi_(21) (for antisymmetric). Hence the condition for satisfying only when the function is equal to zero. Which of the following set of quantum number is incorrect ?

According to molecular orbital theory, atomic orbitals of nearly same energy of different atoms are combined and form molecule. In homodiatomic molecule two atomic orbitals which have wave function psi_(A) and psi_(B) are combined in two ways (psi_(A)pm psi_(B)) . They have two type of electron density, one is bonding [(psi_(A) pm psi_(B))^(2)] where e- density increase between nucleus. Another is antibonding [(psi_(A)pm psi_(B))^(2)] where e^(-) density decreases between nucleus. These molecular orbitals are filled according to Hund, Pauli, afbau principle. Existence of molecule depends on bond order. where bond order = ("Number of bonding "e^(-)"s- number of antibonding "e^(-)s)/(2) lf the molecule have unpaired electron it is paramagnetic otherwise diamagnetic Statement- 1: Removal of two e^(-) from N^(2) , magnetic behaviour does not change while addition of two electrons in O_(2) magnetic behaviour changes. Statement-2: In N_(2) removal of electron talces place from bonding orbital while addition of e^(-) in O_(2) is in antibonding orbital
