Determine the oxidation numbr of C in the following : `C_(2)H_(6),C_(4)H_(10),CO,cO_(2) and HCO_(3)^(-)`

Explanation

To determine the oxidation number of carbon (C) in the given compounds, we will follow a systematic approach using the known oxidation states of hydrogen (H) and oxygen (O).

### Step-by-Step Solution:

1. **For C₂H₆ (Ethane)**:
- Let the oxidation number of carbon be \( x \).
- There are 2 carbon atoms, so the contribution from carbon is \( 2x \).
- Hydrogen has an oxidation state of +1, and there are 6 hydrogen atoms, contributing \( 6 \times (+1) = +6 \).
