Q. The basic character of the transition metal monoxides follows the order
(Atomic numbers: $Ti=22,V=23,Cr=24,Fe=26$ )

NTA AbhyasNTA Abhyas 2022

Solution:

Oxides of transition metals in low oxidation states +2 and +3 (MO, $M_{3}O_{4}$ and $M_{2}O_{3}$ ) are generally basic except $Cr_{2}O_{3}$ which is amphoteric in character.
