Question

The basic character of the transition metal monoxides follows the order

(atomic no’s Ti = 22, V =23, Cr = 24, Fe = 26)

A

VO > CrO > TiO > FeO

B

CrO > VO > FeO > TiO

C

TiO > FeO > VO > CrO

D

TiO > VO > CrO > FeO

Answer

TiO > VO > CrO > FeO

Explanation

Solution

Oxides of transition metals in low oxidation states +2 and +3 (MO, $M_{3}O_{4}$ and $M_{2}O_{3}$ ) are generally basic except $Cr_{2}O_{3}$ which is ampoteric in character. Basic character generally decreases with increase in atomic number.
