Question

The maximum oxidation state of chromium is

• A. +2
• B. +3
• C. +4
• D. +6

Hint:

The maximum oxidation state of transition metals is often their highest possible charge, determined by the loss of electrons from both \( s \) and \( d \) orbitals.

Answer 1

The Correct Option is D

Step 1: Oxidation states of chromium.
Chromium exhibits multiple oxidation states, including +2, +3, +4, and +6. The maximum oxidation state of chromium is +6, which occurs in compounds like chromium trioxide (CrO₃). Step 2: Conclusion.
The correct answer is (D) because the maximum oxidation state of chromium is +6.
