The basic character of the transition metal monoxide follows the order

Options

  1. AVO>CrO>TiO>FeO\mathrm{VO}>\mathrm{CrO}>\mathrm{TiO}>\mathrm{FeO}
  2. BCrO>VO>FeO>TiO\mathrm{CrO}>\mathrm{VO}>\mathrm{FeO}>\mathrm{TiO}
  3. CTiO>FeO>VO>CrO\mathrm{TiO}>\mathrm{FeO}>\mathrm{VO}>\mathrm{CrO}
  4. DTiO>VO>CrO>FeO\mathrm{TiO}>\mathrm{VO}>\mathrm{CrO}>\mathrm{FeO}

Correct answer

D. TiO>VO>CrO>FeO\mathrm{TiO}>\mathrm{VO}>\mathrm{CrO}>\mathrm{FeO}

Step-by-step solution

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