Using structural formula, draw formulae illustrating the complete combustion of ethanol
We can't draw structures on the board.
I'm sure you know the equation.
C2H5OH + 3O2 ==> 2CO2 + 3H2O
for visualization purposes:
C2H5OH is sometimes written as CH3CH2OH
To draw the structural formulae illustrating the complete combustion of ethanol, we need to understand the molecular formula of ethanol and the process of complete combustion.
Ethanol has the molecular formula C2H5OH, meaning it contains 2 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom.
Complete combustion occurs when a fuel (in this case, ethanol) reacts with an oxidizing agent, typically oxygen (O2), in the presence of sufficient heat to produce carbon dioxide (CO2) and water (H2O).
Here's how you can draw the structural formulae step-by-step:
Step 1: Draw the structural formula of ethanol.
CH3CH2OH

H
Step 2: Identify the elements present in ethanol and the products formed during complete combustion (carbon dioxide and water).
Step 3: Separate each element and track their connectivity. Draw a complete structural formula for each compound.
Carbon Dioxide (CO2):
O=C=O
Water (H2O):
H
|
H-O-H
Step 4: Combine the structural formulae to symbolize the complete combustion of ethanol.
EtOH + O2 → CO2 + H2O
CH3CH2OH + 3O2 → 2CO2 + 3H2O
Hence, the structural formulae illustrating the complete combustion of ethanol are:
Ethanol (C2H5OH) + Oxygen (O2) → Carbon Dioxide (CO2) + Water (H2O)
