The basic character of the transition metal monoxide follows the order

Options

A. `VO gt CrO gt TiO gt FeO`
B. `CrO gt VO gt FeO gt TiO`
C. `TiO gt FeO gt VO gt CrO`
D. `TiO gt VO gt CrO gt FeO`

Answer

D

Explanation

Oxides of transition metals in lower oxidation states such as 2 and 3 are generally basic except `Cr_(2)O_(3)`. Basic character of oxides decreases as we move across the series of transition metals. Thus, the correct order of basic character of the transition metal oxides is
`TiO gt VO gt CrO gt FeO`
