Which of the following fuels is considered the cleanest fuel due to absence of carbon in its combustion?
easy Q13 of 15
Step-by-Step Solution
Step 1: Understand clean fuel concept
A clean fuel produces minimal or no pollutants like carbon dioxide, carbon monoxide, or soot during combustion.Step 2: Analyze fuel composition
Hydrogen contains no carbon, so its combustion produces only water vapour.Step 3: Eliminate other fuels
Coal, petrol, and LPG contain carbon and release carbon dioxide on burning.Final Answer:
Hydrogen → Option DQuick Check:
Cleanest fuel (no carbon) = Hydrogen ✅
Quick Trick: No carbon in fuel → Clean combustion → Hydrogen
Common Mistakes:
- Assuming LPG is the cleanest fuel without considering carbon content.
