Aliphatic hydrocarbons are organic hydrocarbon compound containing carbon and hydrogen bonded together in straight chains, branched trains or non-aromatic ring system. Aliphatic compounds may be saturated (e.g., Hexane and other Alkanes) or unsaturated (e.g., Hexene and other Alkene, as well as alkynes).

Definition of Aliphatic Hydrocarbon:Aliphatic hydrocarbons are organic hydrocarbon compound containing carbon and hydrogen bonded together in straight chains, branched trains or non-aromatic ring system. Aliphatic compounds may be saturated (e.g., hexane and other alkanes) or unsaturated (e.g., hexene and other alkene, as well as alkynes).
or anything similar before? If you haven’t seen them, where will you expect to
find them? Maybe in a flammable container in the chemistry lab. Probably on the highway, or on a liquefied dried curvature. Maybe when you’re getting ready to grill, or maybe when you’ve been clamping with a portable stove.

What kind of compounds are these symbols warning us about? What makes them potentially dangerous and highly vulnerable on exposure? Some of the most common, flammable and volatile compounds are aliphatic hydrocarbons.
Part of these classes of compounds are familiar to you. However, does the term hydrocarbon ring any bells?
carbon atoms bonded together through the sharing of electrons. Carbon-based
compounds are often referred to as organic compounds , most belong to the same homologous series and some don’t .More scientifically, Organic compounds are compounds containing carbon to carbon bond linkages either in a straight chain arrangement or in a branch chain arrangement.
some of the first aliphatic compounds discovered came from fats or oil. In our case, aliphatic refers to hydrocarbon compounds that are straight chained, branched or non-aromatic.
compound may be a straight chain made of carbon and hydrogen bonds, like
butane, or it may be branched, like isobutane.
carbons at a time. Look at butane on the left. How many carbons is the end
carbon bonded to? How many carbons are the middle carbons bonded to? In a
branched compound, there may be three or four carbons bonded to a single
carbon. In isobutene, the outside carbons are only bonded to one carbon each,
while the central carbon is bonded to three carbons.
hydrocarbon is cyclic and not especially stable nature, or alicyclic. These
compounds include cycloalicyclic, it can be unsaturated with 4 pie bonds but
certainly lacks aromaticity. methylcyclohexane, and heptalene.
uncommon to have oxygen, nitrogen, sulfur or chlorine atoms present. An aliphatic hydrocarbon can be either saturated or unsaturated . When saturated, a hydrocarbon contains only single bonds and contains the maximum number of hydrogens. Unsaturated hydrocarbons are the opposite. They may have one or more double bonds and less than the maximum number of hydrogens, typically they contain 1 singlw bond and 1 pie
bond for the alkene and 2 pie bond for the alkyne.
least one double bond, then it is known as an alkene. A hydrocarbon that contains at least one triple bond is known as an alkyne. Aliphatic hydrocarbons may be alkanes, alkenes or alkynes.
a very simple aliphatic hydrocarbon, in our homes, fireplaces and even in our
vehicles!
they don’t escape and cause trouble. Methane smells like flame things, which helps us identify when there is a leak.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. This gas is easy to light, so careful!
for. Even solid aliphatic hydrocarbons can ignite. Waxes and fats can sustain a flame
easily.
Basic List of Aliphatic Compounds you should know
Aliphatic compounds are very important, especially in our daily living.Open-chain compounds that contain no rings are aliphatic, irrespective of wether they contain single, double, or triple bonds. However, they might be saturated or unsaturated. Here is a highlighted list of aliphatic compounds, serially arranged according to the number of carbon atoms they contain.
| Number of Carbons | Aliphatic Hydrocarbons |
| 1 | methane |
| 2 | ethane, ethene, ethyne |
| 3 | propane, propene, propyne, cyclopropane |
| 4 | butane, methylpropane, cyclobutene |
| 5 | pentane, dimethylpropane, cyclopentene |
