JEE Main & Advanced Chemistry Chemical Bonding and Molecular Structure / रासायनिक आबंधन एवं आणविक संरचना Question Bank Molecular orbital theory

  • question_answer
    \[PC{{l}_{5}}\] exists but \[NC{{l}_{5}}\]does not because [EAMCET 1977; MP PET/PMT 1988]

    A)                 Nitrogen has no vacant d-orbitals

    B)                 \[NC{{l}_{5}}\]is unstable

    C)                 Nitrogen atom is much smaller

    D)                 Nitrogen is highly inert

    Correct Answer: A

    Solution :

                    Nitrogen does not have vacant ?d?-orbitals so it can?t have +5 oxidation state i.e. the reason \[PC{{l}_{5}}\] exists but \[NC{{l}_{5}}\] does not.
