Q35 E - Chemistry (OpenStax)

Question

Methanol, \({{\text{H}}_{\text{3}}}{\text{COH}}\), is used as the fuel in some race cars. Ethanol, \({{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{OH}}\), is used extensively as motor fuel in Brazil. Both methanol and ethanol produce \({\text{C}}{{\text{O}}_{\text{2}}}\) and \({{\text{H}}_{\text{2}}}{\text{O}}\) when they burn. Write the chemical equations for these combustion reactions using Lewis structures instead of chemical formulas.

Step-by-Step Solution

Answer

The combustion reaction using the Lewis structure for \({\text{C}}{{\text{H}}_{\text{3}}}{\text{OH }}\) is

The combustion reaction using the Lewis structure for \({{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{OH }}\) is:

Step 1: Define Chemical Bonding

A chemical bond is a long-term inducement between atoms, ions, or molecules that permits chemical compounds to develop.

Step 2: Writing the combustion reaction

The combustion reaction for \({\text{C}}{{\text{H}}_{\text{3}}}{\text{OH }}\) is

The combustion reaction for \({{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{OH }}\) 

Therefore, the reactions are 

\({\text{C}}{{\text{H}}_{\text{3}}}{\text{OH }}\)- 

 

\({{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}{\text{OH }}\)-
