MOLECULAR ORBITAL THEORY(QUIZ-3) 1 / 5 On the basis of molecular orbital theory, select the most appropriate option. The bond order of O2 is 2.5 and it is paramagnetic The bond order of O2 is 1.5 and it is paramagnetic The bond order of O2 is 2 and it is diamagnetic The bond order of O2 is 2 and it is paramagnetic Oxygen is paramagnetic in nature and its bond order is 2. It is an exceptional case. 2 / 5 Arrange the following molecules in decreasing bond length. 1 2 3 4 The bond length is inversely proportional to the bond order. Therefore, the correct is:O22- > O2– > O2 > O2+. 3 / 5 Bond Order of O2, F2, N2 respectively are __________ +1, +2, +3 +2, +3, +1 +2, +1, +3 +3, +2, +1 Bond Order=[[Number of electrons in bonding molecular orbital]-[Number of electrons in antibonding molecular orbital]]/2. 4 / 5 The filling of molecular orbital takes place according to __________ The Aufbau Principle Pauli Exclusion Principle Hund’s rule of maximum multiplicity All of the mentioned According to these principles, molecular orbitals are filled in order of increasing energy. Two electrons in the same orbital cannot have the same set of all four quantum numbers identical. 5 / 5 If the sign of the wave function is unchanged when the orbital is reflected about its centre, the orbital is ______________ Gerade Ungerade Gerade as well as Ungerade None of the mentioned If the sign of the wave function is unchanged when the orbital is reflected about its center (i.e., x, y and z are replaced by –x, -y and –z), the orbital is gerade.
