Chemistry Question on d block elements
The basic character of the transition metal monoxides follows the order: (Atomic no. - Ti = 22, V = 23, Cr = 24, Fe = 26)
A
VO > CrO > TiO > FeO
B
CrO >VO > FeO > TiO
C
TiO > FeO > VO > CrO
D
TiO > VO > CrO > FeO
Answer
TiO > VO > CrO > FeO
Explanation
Solution
As the metal ionsize decreases from Ti to Fe, the basic nature of their monoxide decreases. So. the basic character of oxides decreases with an increase in atomic number.
Hence, the basic character of thetransition metalmonoxides follows the order TiO > VO > CrO > FeO.
