**asap** petroleum is a mixture consisting mostly a.) aromatic hydrocarbons b.) methane and long branches alkanes c.) methane, ethane, propane, and isomers of butane d.) long branched alkanes and alkenes

b.) methane and long branches alkanes

Explanation:

Petroleum or crude oil is a fossil fuel formed by the decomposition of organisms buried under the earth's surface and subjected to intense pressure and temperature. It is composed of a mixture of hydrocarbons which include paraffins (linear and branched alkanes), naphthenes (cyclic alkanes) and other aromatic compounds.

However, petroleum is predominantly consists of paraffins which have the general formula CnH2n+2 and include methane and other long branched alkanes.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
