Gasoline use contributes to air pollution
Gasoline is a toxic and highly flammable liquid. The vapors given off when gasoline evaporates and the substances produced when gasoline is burned (carbon monoxide, nitrogen oxides, particulate matter, and unburned hydrocarbons) contribute to air pollution. Burning gasoline also produces carbon dioxide, a greenhouse gas.
You know that each carbon atom can take as much as 4 bonds with other elements. A hydrogen can only take one bond, while an oxygen can take 2. Thus, the chemical formula of H₂CO may be written as H₂C=O which is acetaldehyde. Acetaldehyde is an aldehyde. It has a higher vapor pressure because aldehydes have much stronger bonds than hydrogen bonds in alcohols. Hence, it would need a lot energy, thus higher vapor pressure, to break the bonds of an aldehyde than it would for an alcohol.
