These flammable gases must be properly labeled and stored in pressured vessels so they don't escape and cause trouble.Methane smells like dead things, which helps us identify when there is a leak.If you want to see this property in action, go pour some oil into water and try to get them to mix.The oil is hydrophobic and cannot mix with the water.
Notice that in a straight chain, the carbon atoms are never bonded to more than two carbons at a time. An aliphatic compound may also be non-aromatic, like cyclobutane.Liquid aliphatic hydrocarbons, like butane, hexanes, and octane, have really high vapor pressure.This means that molecules can easily escape the liquid phase and enter the gas phase, leading to high-density collection of gas particles right over the surface of the liquid. A fire started over a flammable liquid is one you need to have an extinguisher for. Waxes and fats can sustain a flame bright enough to read by.When saturated, a hydrocarbon contains only single bonds and contains the maximum number of hydrogens. They may have one or more double bonds and less than the maximum number of hydrogens.When a hydrocarbon has only single bonds, it is known as an alkane.The term aliphatic stems from a Greek word meaning fat or oil.
