Definition of Hexane
Hexane is an organic chemical compound that is classified as an alkane. It is specifically, a straight-chain alkane that has the molecular formula of C6H14. It is part of the family of hydrocarbons, made up of carbon (C) and hydrogen (H) atoms alone and characterized by a linear arrangement of carbon atoms inside the molecular structure.
Hexane is a clear, colorless, and smiling liquid at room temperatures and it is largely insoluble in water. It is frequently utilized in many sectors and uses, like a solvent for the extraction from oil, for the manufacture of adhesives, pharmaceuticals, and paints, as well as a cleaning agent for specific industrial procedures. But, exposure for long periods to hexane may cause health hazards, especially in the respiratory and nervous systems. Therefore, the use of safety precautions in handling the chemical.
Definition of n-Hexane
The organic compound n-Hexane is a compound and is an isomer Hexane. It shares the same molecular formula C6H14. It has distinct structural arrangements of carbon atoms as compared to the straight-chain counterpart of hexane. This is why the n-hexane structure is unique. It consists of six carbon atoms within the linear chain. This makes it unique from other hexane isomers that are branched, like the cyclohexane form.
It is impermeable to water, however, it is dissolved with organic solvents. Its nonpolar properties and superior solvent properties make it useful in a wide range of uses, especially when used in laboratories. The n-Hexane solvent is used extensively as a solvent that is non-polar for chemical reaction, and extraction procedures as well as chromatography processes for industrial and research laboratories.

Thus, safety precautions and adequate ventilation are essential while working with the chemical in order to reduce the risk of exposure.
Difference Between Hexane and n-Hexane
Both are hydrocarbons. This means they’re composed of carbon (C) and hydrogen (H) atoms alone. They are also alkanes. These are which is a form of saturated hydrocarbon. It suggests that all carbon-carbon bonds within their molecular structures are singular bonds.
Chemical Formula: C6H14
Structural Formula: CH3(CH2)4CH3
Explanation: Hexane has a straight-chain structure that has six carbon atoms in one row, each of which is bonded by 2 hydrogen atoms. Its molecular formula C6H14 signifies that it is composed of fourteen hydrogen atoms.
Chemical Formula: C6H14
Structural Formula: CH3(CH2)3CH3
The explanation is that n-Hexane can be described as an isomer of the hexane compound, meaning it uses similar chemical formulas, however with an entirely distinct configuration of carbon atoms. In n-hexane, carbon atoms are arranged in an elongated chain that has five carbon atoms per row. The final carbon atom splits off, with three carbon atoms that are bonded to the. This branching is what gives it the designation “n” for normal hexane.
The bottom line is that each hexane and N-hexane has the same molecular formula, C6H14 however their structures differ. Hexane is a linear chain made of six carbon atoms. In contrast, it has a similar chain, however, with one carbon atom that branches off, and then being joined to three carbon atoms. This structural difference results in the different chemical and physical characteristics, which can lead to different applications in different fields.
