Question

Which of these fuels is a mixture of hydrocarbons? a petrol b cng c lpg d all of these​

Answer 1

Answer:

Diesel fuels are complex hydrocarbon mixtures, containing all the classes of hydrocarbons: paraffins, naphthenes, aromatics, and in small concentrations, olefins.

Answer 2

Answer:

Diesel Composition

Diesel fuels are complex hydrocarbon mixtures, containing all the classes of hydrocarbons: paraffins, naphthenes, aromatics, and in small concentrations, olefins. They are manufactured to meet the property limits of the specifications and regulations, and not to achieve a specific hydrocarbon distribution by class and size. But, to varying degrees, the property limits define the chemical composition of the fuel. The volatility of a diesel fuel is expressed by its distillation curve. Each individual hydrocarbon boils at a specific temperature called its boiling point and, in general, the boiling point increases with molecular size. Consequently, defining a distillation curve is equivalent to defining a certain distribution of hydrocarbons with a range of sizes.. The temperature limits of the distillation curve exclude smaller hydrocarbons with lower boiling points and larger hydrocarbons with higher boiling points.
