Question

This oxide is most basic. [Ti=22, V=23, Cr=24, Fe=26]

• A. FeO
• B. VO
• C. CrO
• D. TiO

Hint:

Basicity of metal oxides increases as the oxidation state decreases, and Titanium(II) oxide is a strong base.

Answer 1

The Correct Option is D

Step 1: Metal Oxide Identification and Properties
The metals are Titanium (Ti), Vanadium (V), Chromium (Cr), and Iron (Fe). Each forms an oxide with varying basicity, which generally correlates with the metal's periodic table position.
Step 2: Option Analysis

• FeO (Iron(II) oxide): Moderately basic, but less so than Titanium oxides.
• VO (Vanadium monoxide): Vanadium oxides are typically less basic and more acidic.
• CrO (Chromium(II) oxide): Exhibits moderate basicity, not the most basic.
• TiO (Titanium(II) oxide): Highly basic due to Titanium's low electronegativity and high metallic character.

Step 3: Conclusion
Titanium oxide (TiO) is the most basic oxide among the choices. This is because Titanium has a lower oxidation state and its oxide demonstrates strong basic behavior.
Conclusion:

TiO is the most basic oxide.
