To solve the question regarding the assertion and reasoning about the B2 molecule, we will follow these steps: ### Step 1: Understand the Assertion The assertion states that the B2 molecule is diamagnetic. Diamagnetism occurs when all electrons in a molecule are paired. If there are unpaired electrons, the molecule is paramagnetic. ### Step 2: Determine the Electron Configuration of B2 Boron (B) has an atomic number of 5, which means its electron configuration is: - 1s² 2s² 2p¹ ...

Assertion : Noble gases are diamagnetic atoms Reason :The atomic numbers of noble gases are even and all the orbitals are doubly occupied by the electrons

The distribution of electrons among molecular orbitals is called the electronic configuration of the molecule which provides us the following very important informations about the molecule. (A)Stability of molecule : The molecule is stable if number of bonding moleculer orbital electrons (N_b) is greater than the number of antibonding molecular orbital electrons (N_a) . (B) Bond order : Bond order =1/2(N_b-N_a) A positive bond order means a stable molecule while a negative or zero bond order means an unstable molecule. ( C)Nature of the bond : Bond order 1,2 and 3 corresponds to single , double and triple bonds respectively. (D)Bond length: Bond length decreases as bond order increases. (E)Magnetic nature: Molecular orbitals in a molecule are doubly occupied , the substance is diamagnetic and if one or more molecular orbitals are singly occupied, it is paramagnetic. Which of the following statements is incorrect ?

Calculate expression (x+y+z) for diatomic molecules. where x=Total number of singly occupied molecular orbital (SOMO) in O_(2) . y=Total number of singly occupied molecular orbital (SOMO) in B_(2) z=Total number of singly occupied molecular orbital (SOMO) in NO .
