The basic character of the transition metal monoxide follows the order:

TiO > VO > CrO > FeO

The correct answer is (2), TiO > VO > CrO > FeO.

The basic character of transition metal monoxides decreases as the atomic number of the metal increases. This is because the effective nuclear charge increases as the atomic number increases, which makes it more difficult for the metal to lose electrons and form a basic oxide.

Therefore, the basic order of the transition metal monoxides is:

• TiO
• VO
• CrO
• FeO
