    Cu²+ is d⁹ configuration. it has unpaired eletron. NO & NO2 too have unpaired eletron.
  • Priyanshu kumar thankyou
    No2 is paramagnetic but its dimer is diamagnetic

    NO2 and NO have odd electrons and exit as dimer while Cu2+ have d8 configuration, d2sp3 hub so doesn't have lp so option A,C,D are incorrect

    Ag+ have d10 electrons so doesn't have lp and is diamagnetic
