Answer

The incomplete combustion of ethanol can be represented by the equation:

C2H5OH(l)+3O2(g)→2CO2(g)+3H2O(l)C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

However, in incomplete combustion, typically carbon monoxide (CO) is produced instead of carbon dioxide (CO2). An incomplete combustion reaction for ethanol can be best described by option D:

C2H5OH(l)+3O2(g)→2CO(g)+3H2O(l)C2H5OH(l) + 3O2(g) → 2CO(g) + 3H2O(l)

Thus, the answer is option D.
