The basic character of the transition metal monoxides follows
the order
(Atomic Nos.,Ti = 22, V = 23, Cr = 24, Fe = 26)
(a) TiO > VO > CrO > FeO (b) VO > CrO > TiO > FeO
(c) CrO > VO > FeO > TiO (d) TiO > FeO > VO > CrO

TiO > VO > CrO > FeO is the correct order.
Explanation:
- The transitional metals are the elements which have the electrons in the 3d shells.
- The transitional metals have electrons in d group whose permeability is very high.
- So as the nuclear charge increase, the atoms become remarkably smaller.
- As the effect of the nuclear charge increase, the bond of the atoms become remarkably covalent.
- The bond length decrease and the bond strength increase.
- So the bond breaking becomes very difficult and basicity decrease.
- So the correct order is TiO > VO > CrO > FeO.
