The first transition series metal ' M ' has the highest enthalpy of atomisation in its series. One of its aquated ion \(\left(\mathrm{M}^{\mathrm{n} \dagger}\right)\) exists in green colour. The nature of the oxide formed by the above \(\mathrm{M}^{\mathrm{n}-}\) ion is _______.
- A neutral
- B acidic
- C basic
- D amphoteric
Answer & Solution
Correct Answer
(C) basic
Step-by-step Solution
Detailed explanation
In 3d series Vanadium has highest enthalpy of atomization and colour of \(\mathrm{V}^{+3}\) is green. * Oxide form by \(\mathrm{V}^{+3}\) is \(\mathrm{V}_2 \mathrm{O}_3\) (Basic oxide)
