The dand fblock elements - Result Question 27

####27. The basic character of the transition metal monoxides follows the order

(Atomic No., Ti=22,V=23,Cr=24,Fe=26 )

(a) TiO>VO>CrO>FeO

[2003]

(b) VO>CrO>TiO>FeO

(c) CrO>VO>FeO>TiO

(d) TiO>FeO>VO>CrO

Show Answer

Solution:

  1. (a) The basic character of the transition metal monoxide is TiO>VO>CrO>FeO because basic character of oxides decrease with increase in atomic number.

Oxides of transitional metals in low oxidation state i.e., +2 and +3 are generally basic except Cr2O3.
