The answer is that hexane and n-hexane are related as n-hexane is an isomer of hexane and the key difference is in their structures. Hexane has a branched structure and n-hexane has an unbranched structure.

The letter n is used in front of hexane in order to differentiate the normal straight-chain hexane from its isomers.
Health Hazards Associate with Hexane
Chronic exposure can cause more severe damage to the nervous system. If swallowed, it may cause severe abdominal pain and impact the respiratory system, resulting in shortness of breath, coughing, burning of the mouth, throat or chest, and even chemical pneumonitis.
n-Hexane is a very volatile aliphatic hydrocarbon. ... “Hexane” or “hexanes” is a commercial and industrial product consisting of a mixture of hydrocarbons with six carbon atoms and includes n-hexane and its isomers 2-methylpentane and 3-methylpentane as well as small amounts of other hydrocarbons (Brugnone et al. 1991).
Pure n-Hexane is a colorless liquid with a slightly disagreeable odor. It is highly flammable, and its vapors can be explosive.
Thus neither hexane nor iodine dissolves in water. Polar and ionic solutes do not dissolve in non-polar solvents because they have a stronger attraction for each other than for the non-polar solvent molecules.
n-Hexane is a FLAMMABLE LIQUID.
The normal boiling point of hexane is 69 °C; that of butane is 0 °C. ... However, interactions BETWEEN the chains can occur, i.e. dispersion forces, and the LONGER the hydrocarbyl chain the greater the force of interaction, and the HIGHER the boiling point. Since hexane has a six-carbon chain it is the more involatile.
Explain. Hexane reached a lower minimum temperature than heptane. This means that hexane evaporated more quickly than heptane. Hexane and heptane have very similar structures—they are both nonpolar hydrocarbons consisting of C—C and C—H bonds.
