Is Hexane, Heptane, Toluene and Br2 Polar or Non-polar

Is Hexane polar or nonpolar?

What exactly is hexane? Hexane is a hydro carbonic compound that comes in classifying alkanes having a formula or C6H14. So what is happening here in the structure is that six atoms of oxygen are connected to corresponding hydrogen atoms. Polarity is the account of how the electric charge is distributed across the molecule.

Hexane is nonpolar because of its C–H bonds and symmetrical geometric structure. The electronegativity difference between carbon and hydrogen is 0.35, indicating that the molecule is nonpolar. Even if C–H bonds were polar, hexane would be nonpolar due to its symmetric geometric structure.

If C–H bonds were polar, the symmetric design of hexane would ensure that each C–Another cancels out the H bond’s partial charge. There is no net dipole moment in the whole molecule.

Hexane is partially polar due to Vander waals forces etc. But for practical purposes, the hexane is nonpolar. Hexane is a colorless liquid at room temperature, and its boiling point is about 50 degrees Celsius. The electronegativity difference of both hydrogen and oxygen is 0.3. So as the net dipole moment is zero, hexane is nonpolar overall in nature.

It is used as a nonpolar solvent and used to dissolve nonpolar compounds. Hexane is widely used in gasoline, glue, varnishes, and inks. It is sometimes used as a cleaning agent in the textile and furniture industries. Sometimes it is used as glue specially used for rooftops and leather products.

Is Heptane polar or nonpolar?

Heptane has a chemical formula of  C7H16, and it comes under the family of alkanes as well, similar to hexane. Hexane is widely used in laboratories and is best carried out for transportation and storage. It is mainly used to dissolve oil spots. When it comes to polarity, heptane is a nonpolar molecule because of the equal number of electrons. 

The polarity is the measure of the dipole moment of any element,  So whichever molecule has the dipole moment is polar, and whichever molecule hasn’t is nonpolar Nonpolar molecules don’t have polar bonds in their molecules. In contrast, polar compounds have polar bonds due to a difference in electronegativity.

In the case of heptane, there is no electronegativity difference between C and H atoms. So there aren’t any polar bonds between them. As a result, the heptane is nonpolar. It is widely used as a nonpolar solvent. Heptane is also used as an industrial cleaner due to its best anti-aging ability, and the same goes for hexane. However, heptane is less toxic than hexane despite belonging to the same. Both are nonpolar in nature. Heptane is less polar than hexane. Heptane has seven carbon atoms, while hexane has six. 

Is toluene polar or nonpolar?

Toluene has a chemical formula of C7H8. The name methylbenzene is also known. It belongs to the group alkenes. Alkenes have two double bonds in their compounds. Bonds between atoms with related electronegativities, such as carbon and hydrogen, exist in different solvents. Toluene, like gasoline, is a hydrocarbon. Polar solvents contain particles with various electronegativities, such as hydrogen and oxygen. When it comes to the polarity of the toluene, it is also nonpolar.

I also have zero dipole moments. And there is no electronegativity difference between the bonds. There isn’t any polar bond within a molecule. That’s why it is widely considered a nonpolar element. It is also widely used as a nonpolar solvent. Toluene, as a hydrocarbon, is a molecule in which all bonds are nonpolar, making it a nonpolar molecule.

Toluene is primarily used as a gasoline additive to increase octane ratings. Toluene is also used to synthesize benzene and as a solvent in coatings, paints, fragrances, cleaning agents, and inks. Toluene can also be used to create polymers used to make nylon, plastic bottles, polyurethanes, pharmaceuticals, and cosmetic nail products. Breathing in toluene-contaminated air is hazardous and depresses the central nervous system.

Is br2 polar or nonpolar?

Br2 is the chemical formula of the diatomic bromine. As the name represents, it is produced when two bromine atoms are combined through a bond. It usually comes in a red-brown liquid. Sometimes upon heating, it gives some toxic vapors, which can be dangerous. When we talk about room temperature, it is considered the halogen compound. And it evaporates like a gas.

Coming to the question as Br2 is made up of two bromine atoms, and they have the same electronegativity values, which results in zero dipole moment. When there is zero dipole moment, there is no polar bond and thus resulting in the whole molecule being nonpolar. So does it have an ionic bond? No, It does have a covalent bond, and the covalent bond between its atoms isn’t polar. They are nonpolar. Thus Br2 is nonpolar in nature overall. It has a linear structure. 

Bromine is a highly reactive element, so when it makes a bond, the resultant compound is also highly reactive, so it is better not to use Br2 usually. Diatomic bromine can be used in fire extinguishers, insecticides, medicines, water purification, etc. 


Hexane and heptane both belong to the same family of hydrocarbon compounds. They belong to alkanes, and they both have almost the same polarity level. They both are nonpolar solvents. They only dissolve inorganic compounds and non polar compounds. They are widely used as nonpolar solvents and are very approachable for transportation and storage. Toluene, on the other hand, is less nonpolar than both. Toluene is also used as a nonpolar solvent. It can also dissolve other nonpolar solvents like hexane and heptane.

Likewise, Br2 is also a nonpolar compound but toxic and dangerous as it is made from bromine, a highly toxic element that is not easily found freely in nature. All of the above 4 compounds hexane, heptane, toluene and diatomic bromine (Br2) are highly non polar in nature.
