The basic character fo the transition metal monoxides follows the order (Atomic no's. Ti = 22, V = 23, Cr = 24 , Fe = 26)

A

VO gt CrO gtTiO 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

Text Solution

Verified by Experts

The correct Answer is:
D
Oxides of transition metals in low oxidation states +2 and +3 `(MO,M_2O_4 and M_2O_3)` are gencerally basic except `Cr_2O_3` which is amphoteric in character.
Basic character generally decreases with increase in atomic number.
