The basic character of the transition metal monoxides follows the order (Atomic Nos., $\mathrm{Ti}=22, \mathrm{~V}=23, \mathrm{Cr}=24, \mathrm{Fe}=26$ )
  1. $\quad \mathrm{TiO}>\mathrm{VO}>\mathrm{CrO}>\mathrm{FeO}$
  2. $\mathrm{VO}>\mathrm{CrO}>\mathrm{TiO}>\mathrm{FeO}$
  3. $\quad \mathrm{CrO}>\mathrm{VO}>\mathrm{FeO}>\mathrm{TiO}$
  4. $\quad \mathrm{TiO}>\mathrm{FeO}>\mathrm{VO}>\mathrm{CrO}$

Solution

The order of basic character of the transition metal monoxide is $\mathrm{TiO}>\mathrm{VO}>\mathrm{CrO}>\mathrm{FeO}$
because basic character of oxides decreases with increase in atomic number.
