  • question_answer
    The basic character of the transition metal monoxides follows the order (Atomic number, Ti = 22, V = 23, Cr = 24, Fe = 26)

    A) TiO > VO > CrO > FeO

    B) VO > CrO > TiO > FeO

    C) TiO > FeO > VO > CrO

    D) CrO > VO > FeO > TiO

    Correct Answer: A

    Solution :

    [a] \[TiO>VO>CrO>FeO\] With the decrease in size of metal atom from Ti to Fe, the basic character or their monoxides decreases.
