    example No2 is odd electron species it also dimerises to form N204 in which electrons get paired

    yes for octet completion

    BeCl2​ exist as dimer below 1200K and monomer above 1200K and monomer exists in vapour phase as in solid phase it polymerized. Structure of BeCl2​ is polymer is similar to to Be hydride polymer but bonding id different. Both show clustring and halide have halogen bridge

    It has only four electrons in valence shell and can accept two pairs of electrons from neighbouring chlorine atoms to complete their octet. In the vapour state, beryllium chloride exists as a dimer (Be2Cl4) which dissociates at 1200 K into monomer (BeCl2) which has a linear shape.
