Question : What is the product formed when CH3CH2OH reacts with O2?
Option 1: H2O+ heat
Option 2: CO2 + H2O + heat and light
Option 3: CO2 + H2O
Option 4: CO2 + heat and light
Correct Answer: CO 2 + H 2 O + heat and light
Solution : The correct option is CO 2 + H 2 O + heat and light .
When Ethanol (CH 3 CH 2 OH) reacts with oxygen (O 2 ) in the presence of a suitable catalyst, combustion occurs, leading to the formation of carbon dioxide (CO 2 ) and water (H 2 O). The balanced chemical equation for the combustion of ethanol is as follows:
C 2 H 5 OH + 3 O 2 → 2 CO 2 + 3 H 2 O (l)
This equation indicates that one molecule of ethanol reacts with three molecules of oxygen to produce two molecules of carbon dioxide and three molecules of water.
