Does anyone know thestructure of petroleum ether?
i've tried chemfinder and it has nostructure.

Petroleum ether is a volatile liquid distilled from petroleum, consisting of a mixture of hydrocarbons.

The structure is attached

Explanation:This petroleum fraction consists of aliphatic hydrocarbons and boils in the range 35-60° C; it is commonly used as a laboratory solvent.

Irrespective of the name, this petroleum fragment is not classified as an ether; the name and term is used only figuratively, showing its extreme lightness and volatility.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
