What is the Chemical Formula of Diesel?

In summary, for a school assessment task, the chemical formula for diesel is commonly written as C12H23. However, this is only the empirical formula and does not provide any structural information about the fuel. It is a mixture of various hydrocarbons and cannot be categorized as an alkane, alkyne, or alkene based on this formula alone. The empirical formula only gives the ratio of carbon to hydrogen and is used to determine the stoichiometry of combustion. It cannot distinguish between different types of compounds, such as alkenes, cyclic structures, or dienes. Therefore, the empirical formula is not the same as the structural formula for diesel.

Homework Statement


For a assessment task at school, I have to compare various types of fuel, one of which is diesel. One aspect of the task is to name the chemical formula for each fuel.

The Attempt at a Solution


I keep finding that the formula for diesel is C12H23. I know that diesel is made up of various hydrocarbons, but C12H23 is niether a alkane, alkyne or alkene. Is C12H23 the correct formula, and if so, what is the structural formula

It's a mixture of things as you noted. The (weighted) average empirical formula contains absolutely no structural information. It only gives you ratios between carbon/hydrogen which is only helpful to determine the stoichiometry of combustion. You can't tell from looking at the empirical formula the difference between a compound that is an alkene or if it contains a cyclic structure either. Or one that is an alkyne from a diene from a bicyclic.

Empirical formula is not the same as structural formula.

What is the chemical formula of diesel?

The chemical formula of diesel can vary depending on the specific composition, but it is typically a complex mixture of hydrocarbons with the general formula C12H23.

How is diesel different from gasoline?

Diesel and gasoline have different chemical formulas and compositions, leading to different properties and uses. Diesel has a higher boiling point and is less flammable than gasoline, making it more suitable for use in diesel engines.

Why is sulfur content important in diesel?

Sulfur content is important in diesel because it can have a significant impact on emissions and air pollution. Higher sulfur content can contribute to the formation of sulfur dioxide, a major air pollutant.

Can diesel be used as a substitute for other fuels?

Diesel can be used as a substitute for other fuels, such as gasoline or biodiesel. However, it is important to consider the specific properties and composition of diesel in order to determine its suitability for a particular use.

How is the chemical formula of diesel determined?

The chemical formula of diesel is determined through various analytical techniques, such as gas chromatography and mass spectrometry. These methods allow for the identification and quantification of the specific hydrocarbons present in the diesel mixture.
