A) \[TiO>FeO>VO>CrO\]
B) \[TiO>VO>CrO>FeO\]
C) \[VO>CrO>TiO>FeO\]
D) \[CrO>VO>FeO>TiO\]
Correct Answer: B
Solution :
[b] The order of basic character of the transition metal monoxide is \[TiO>VO>CrO>FeO\] because basic character of oxides decrease with increase in atomic number. Hence, oxides of transitional metals in low oxidation state i.e., +2 and +3 are generally basic except \[C{{r}_{2}}{{O}_{3}}\]. (Atomic number \[Ti=22,\text{ }V=23,\text{ }Cr=24,\] \[\text{ }Fe=26\])You need to login to perform this action.
