n-hexane is also a structural isomer of hexane. Therefore, both these compounds have the same chemical formula and the same molar mass. The main difference between hexane and n-hexane is that hexane has 5 structural isomers that are either branched or unbranched structures whereas n-hexane is an unbranched structure.
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.
The major use for solvents containing n-hexane is to extract vegetable oils from crops such as soybeans. These solvents are also used as cleaning agents in the printing, textile, furniture, and shoemaking industries.
Hexane is non-polar. This is because it is made of carbon and hydrogen. Although there is a difference in their electronegativity on Pauling scale but it is less than 0.5( it is 0.4 approximately) and for significant dipole moment the electronegativity difference should be more than or equal to 0.5.
Acute (short-term) inhalation exposure of humans to high levels of hexane causes mild central nervous system (CNS) effects, including dizziness, giddiness, slight nausea, and headache. ... EPA has classified hexane as a Group D, not classifiable as to human carcinogenicity.
Hexane has been widely used for oil extraction because of easy oil recovery, narrow boiling point (63–69 °C) and excellent solubilizing ability . In contrary, while in extraction and recovery processes, hexane is released into the environment that react with the pollutants to form ozone and photo chemicals .
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.
Products where hexane is found
Common household products, such as spray adhesives, contact cement, arts and craft paints, and stain removers contain hexane.
Hexane (/ˈhɛkseɪn/) is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C6H14.
n-Hexane is a very volatile aliphatic hydrocarbon. ... Laboratory and industrial solvents such as “hexane” and petroleum ether contain n-hexane from <0.1% to as much as 33% (Creaser et al.1983).
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.
