Question

Among the following which is saturated aliphatic hydrocarbon?
A.${{C}_{6}}{{H}_{6}}$
B.${{C}_{6}}{{H}_{12}}$
C.${{C}_{6}}{{H}_{14}}$
D.All of these.

Answer 1

Hint: We know that the hydrocarbons get classified into two broad categories: aliphatic hydrocarbons and aromatic hydrocarbons. The term aliphatic comes from the Greek word ‘Aleiphar,’ which means ‘fat.’ It refers to hydrocarbons obtained by the chemical degradation of oils or fats. An aliphatic compound is an organic one.

Complete answer: Let’s define what saturated hydrocarbons are. Saturated hydrocarbons are defined as hydrocarbons that contain only single bonds between the carbon atoms. In other words, each carbon atom is bonded to as many hydrogen atoms as possible and no multiple bonds are present between the carbon-carbon atoms. We can also say that the carbon atoms are saturated with hydrogen. They are the simplest class of hydrocarbons. Saturated hydrocarbons are given the general name of alkanes.
An aliphatic compound or aliphatic hydrocarbon contains hydrogen and carbon atoms linked together in straight chains. Sometimes, the chains can also occur in branched form or non-aromatic structures. Keep in mind that aliphatic compounds are organic. Apart from the hydrogen, different elements like oxygen, nitrogen, chlorine, and sulfur may get joined with the carbon atoms in the chain. Halogenated aliphatic hydrocarbons are chemicals where one or more hydrogen atoms get replaced by the halogen.
Aliphatic hydrocarbons encompass a diverse group of organic compounds characterized by different single, double, and triple bonds, and an open-chain structure as well. Below is a classification of hydrocarbons; as you can see, there are four types of aliphatic compounds. They are alkanes, alkenes, alkynes, and cyclic or cyclic-alkanes. ${{C}_{6}}{{H}_{14}}$is a member of the alkene family. Hence it is a saturated aliphatic hydrocarbon.
Therefore, the correct answer is option C.

Note:
Remember that each carbon atom is bonded to as many hydrogen atoms as possible and no multiple bonds are present between the carbon-carbon atoms. We can also say that the carbon atoms are saturated with hydrogen. They are the simplest class of hydrocarbons. Saturated hydrocarbons are given the general name of alkanes.
