JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure Question Bank Critical Thinking

  • question_answer \[{{N}_{2}}\] and \[{{O}_{2}}\] are converted into monocations \[N_{2}^{+}\] and \[O_{2}^{+}\] respectively. Which is wrong   [CBSE PMT 1997]

    A)                 In  \[{{N}_{2}},\] the \[N-N\]bond weakens

    B)                 In \[{{O}_{2}},\] the \[O-O\] bond order increases

    C)                 In \[{{O}_{2}},\] paramagnetism decreases

    D)                 \[N_{2}^{+}\] becomes diamagnetic

    Correct Answer: D

    Solution :

                    \[N_{2}^{+}\] has one unpaired electron so it would be paramagnetic.
