Question

Which of the following oxides will be the most basic: Ti (22), V (23), Cr (24), Fe (26)?

• A. Ti (Titanium)
• B. V (Vanadium)
• C. Cr (Chromium)
• D. Fe (Iron)

Hint:

The basicity of oxides decreases as you move across a period from left to right and increases down a group.

Answer 1

The Correct Option is A

Step 1: Oxide Basicity Trend
Oxide basicity generally increases left across a period and decreases down a group.
Titanium (Ti) exhibits the most basic oxide among the provided elements.
Step 2: Option Evaluation

• Option (1): Ti (Titanium): Titanium's most basic oxide, TiO₂, is due to its periodic table position (group 4).
• Option (2): V (Vanadium): Vanadium's oxide is less basic than Titanium's.
• Option (3): Cr (Chromium): Chromium's oxide is acidic.
• Option (4): Fe (Iron): Iron's oxide is amphoteric, less basic than Titanium's.

Step 3: Conclusion
Titanium forms the most basic oxide.
Conclusion:

Ti forms the most basic oxide.
