Why does a substance containing only long hydrocarbon chains would not be a good emulsifer for mixtures of water and oil?

Water is a polar solvent, hydrocarbons(oli) non-polar solvents. An emulsifier must be both polar and non-polar, that is , one end of the molecule is polar and will bond with water and the other end non-polar and capable of bonding with the hydroncarbon.

∙ 12y agoAn emulsifier "ties together" substances of differing polarities. Water is very polar and would attract ionically bonded substances. Oil is very hydrophobic and would thus need something very non-polar to attract it. The ideal emulsifier for oil and water would thus have a very non-polar tail and an ionic (very polar) head. A substance with only ionic bonds would only attract the water and not the oil and would thus be a very poor emulsifier.

No, Petrol etc are mixtures of hydrocarbon compounds
How you differentiate substance from mixtures?
Substance would be what goes together with other substance to make a mixture.

What are the characteristics of substance and mixtures?
Mixtures: can be separated by physical means
What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
