The basic character of the transition metal monoxide follows the order

The basic character of the transition metal monoxide follows the order
  1. $\mathrm{VO}>\mathrm{CrO}>\mathrm{TiO}>\mathrm{FeO}$
  2. $\mathrm{CrO}>\mathrm{VO}>\mathrm{FeO}>\mathrm{TiO}$
  3. $\mathrm{TiO}>\mathrm{FeO}>\mathrm{VO}>\mathrm{CrO}$
  4. $\mathrm{TiO}>\mathrm{VO}>\mathrm{CrO}>\mathrm{FeO}$

Solution

As the size of the metal atom decreases from Ti to $\mathrm{Fe}$, basic character of their monoxide decreases in the same order.
