The basic character fo the transition metal monoxides follows the order (Atomic no's. Ti = 22, V = 23, Cr = 24 , Fe = 26)

Options

A. 1. VO > CrO > TiO > FeO
B. 2. CrO > VO > FeO > TiO
C. 3. TiO > FeO > VO > CrO
D. 4. TiO > VO > CrO > FeO

Explanation

To determine the order of basic character for the transition metal monoxides (TiO, VO, CrO, FeO), we can analyze the transition metals mentioned: Titanium (Ti), Vanadium (V), Chromium (Cr), and Iron (Fe). The atomic numbers are as follows: Ti = 22, V = 23, Cr = 24, and Fe = 26.

### Step-by-Step Solution:

1. **Understanding Basic Character**: The basic character of metal oxides generally decreases as we move from left to right across the periodic table. This is because the electronegativity of the elements increases, making their oxides less basic.

2. **Identifying the Elements**: The elements in question are:
- Titanium (Ti) - Atomic number 22
- Vanadium (V) - Atomic number 23
- Chromium (Cr) - Atomic number 24
- Iron (Fe) - Atomic number 26

3. **Order of Basic Character**: Based on the trend that basic character decreases with increasing atomic number:
- Titanium (Ti) being the first in the series will have the highest basic character.
- Vanadium (V) will have a lower basic character than Titanium.
- Chromium (Cr) will have a lower basic character than Vanadium.
- Iron (Fe) will have the lowest basic character among these four.

4. **Final Order**: Therefore, the order of basic character for the transition metal monoxides is:
- TiO > VO > CrO > FeO

### Conclusion:
The basic character of the transition metal monoxides follows the order: **TiO > VO > CrO > FeO**.
