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
The basicity of an oxide generally increases as you move left across a period and decreases as you move down a group.
Titanium (Ti) has the most basic oxide among the elements given.
Step 2: Evaluate the options

• Option (1): Ti (Titanium): Titanium has the most basic oxide, TiO₂, due to its position in the periodic table (group 4).
• Option (2): V (Vanadium): Vanadium's oxide is less basic compared to Titanium.
• Option (3): Cr (Chromium): Chromium's oxide is acidic in nature.
• Option (4): Fe (Iron): Iron's oxide is amphoteric, meaning it exhibits both acidic and basic properties but is less basic than Titanium.

Step 3: Conclusion
Titanium forms the most basic oxide compared to the others.
Conclusion:

Ti forms the most basic oxide.
