Hint: Kerosene is a mixture of hydrocarbons consisting of 10different types of hydrocarbons, each containing 10to16different carbon atoms per molecule. The main constituents of kerosene are- saturated straight-chain and branched-chain paraffin, as well as ring-shaped cycloparaffins (also known as naphthenes). Although kerosene is less volatile than gasoline, it has a flash point (temperature at which it will generate flammable vapor near its surface) is 38C or higher.

Complete answer: As we know, kerosene consists of 10different types of hydrocarbons, the chemical composition depends on its source. Kerosene is a petroleum distillate which includes fractions with boiling points between 150Cto300C.
Therefore, the structural formula of kerosene isC12H26C15H32.
We can also write the structure of kerosene as:

Note:
Like diesel, kerosene is also a straight-run fraction of petroleum and it is used as jet fuel as well as for domestic purposes. Kerosene is a low viscosity, clear liquid that is formed from the hydrocarbons obtained from fractional distribution of petroleum and has a density of 0.780.81gcm3. It is mostly a mixture of hydrocarbons ranging from C10to C16 and must be free of aromatic and saturated hydrocarbons, as well as sulfur compounds. Typically, kerosene consists of nalkanes, alkyl benzenes and naphthalenes.
