Question:
The oxidation numbers of carbon and hydrogen in methane are respectively
The oxidation numbers of carbon and hydrogen in methane are respectively
Show Hint
Hydrogen is +1 with non-metals and -1 with metals (hydrides).
Updated On: Apr 27, 2026
- +4 and +1
- +4 and 0
- -4 and +1
- -4 and -1
- +4 and -1
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Hydrogen in compounds with non-metals has an oxidation state of +1.
Step 2: Meaning
The sum of oxidation states in a neutral molecule ($CH_4$) must be zero.
Step 3: Analysis
$x + 4(+1) = 0 \Rightarrow x + 4 = 0 \Rightarrow x = -4$.
Step 4: Conclusion
Carbon is -4 and Hydrogen is +1. Correct answer is (C).
Final Answer: (C)
