The first transition series metal ' M ' has the highest enthalpy of atomisation in its series. One of its aquated ion (Mn†)\left(\mathrm{M}^{\mathrm{n} \dagger}\right) exists in green colour. The nature of the oxide formed by the above Mn−\mathrm{M}^{\mathrm{n}-} ion is :

Options

  1. Aneutral
  2. Bacidic
  3. Cbasic
  4. Damphoteric

Correct answer

C. basic

Step-by-step solution

* In 3d series Vanadium has highest enthalpy of atomization and colour of V+3\mathrm{V}^{+3} is green.
* Oxide form by V+3\mathrm{V}^{+3} is V2O3\mathrm{V}_2 \mathrm{O}_3 (Basic oxide)
