  • question_answer
    Although\[~C{{N}^{-}}\] ion and \[{{N}_{2}}\] molecule are isoelectronic, yet\[{{N}_{2}}\] molecule is chemically inert because of

    A) presence of more number of electrons in bonding orbitals

    B) lone bond energy

    C) absence of bond polarity

    D) uneven electron distribution.

    Correct Answer: C

    Solution :

    [c] In nitrogen molecule, both the nitrogen atoms have same electronegativity. So it has zero polarity and hence less tendency to break away and form ions.
