Bromine is a chemistry compound through chemical formula Br2. The exists as a fuming red-brown colored fluid at room temperature. It conveniently gets evaporate to type same-color gas. In the regular table, the is positioned in ~ the third lightest halogen place. Many human being have doubts about whether Br2 is polar or not. In this article, I will certainly answer this question and also will covering its properties and applications.

You are watching: Br2 polar or nonpolar or ionic

So, Is Br2 Polar or Nonpolar? Br2 (Bromine) is nonpolar because, in this molecule, both bromine atoms have actually the same electronegativity due to which both atoms have equal charge distribution and results in a net-zero dipole moment. It is linear in structure.

At room temperature, Bromine exists in a liquid state with reddish-brown texture. That is volatile in nature, readily evaporates in the kind of a gas.

It is classified as a halogen compound. Few examples of such compounds are chlorine, fluorine.

The atomic number of bromine is 35. It has one valence electron in the outermost digital configuration.


The chemistry composition that the bromine molecule consists of two atom of bromine and forms the molecular weight amounts to to 79.904 g/mol.

The Bromine is a very reactive substance and it does no occur freely in nature. The vapors the bromine gas are an extremely toxic throughout inhalation. That can reason irritation in the throat and also eyes.

If we talk around the chemical framework of Bromine molecule, it is a linear-shaped molecule that has two bromine atoms at both end covalently bonded.

Both atom share one electron that each various other to complete their octet.

The electronegativity of Bromine atom is 2.96. As both atoms have actually the exact same electronegativity, therefore, both of these atoms have equal influence on the external inspection pair that electrons.

Electronegativity of one atom is the stamin with which it can lure the bonded pair that electrons.

Due come the over reason, the bromine molecule is nonpolar in nature.

What are Polar and Nonpolar Molecules?

The atoms in the molecules are organized by the link forces. The varieties of the bond have the right to be ionic, covalent, metallic, and also hydrogen bond.

The covalent and also ionic have actually much greater strength as contrasted to other species of bonds.

The covalent bonds have the right to have polarity depending upon various factors.

Polar Molecules: These are the molecules that have actually atoms covalently bonded and also have uneven charge circulation on them.

The covalent bond in between two atoms is said to be polar if both atoms differ in their electronegativity because of which they share an unequal proportion the charge.These molecules have actually non zero dipole moment. Few examples of such molecules space IF5, HO2, etc. You can inspect out the reason for the polarity that IF5.

Non-Polar Molecule: These room the molecule that have actually covalently bonded atoms having actually equal distribution of fee on them.

The bond developed by two atoms is claimed to be nonpolar if they have equal electronegativity as result of which lock share an same proportion the charge.

Examples of such molecules space Hexane, CO2, etc. Girlfriend can inspect out the reason for the non-polarity the Hexane.

Note: the is feasible that a geometrically symmetric shame non-polar molecule have the right to have a polar bond in ~ it. Yet due to its symmetric shape, the polarity it s okay canceled by each other resulting in a nonpolar molecule.

Why is Br2 a Nonpolar Molecule?

The bromine molecule has actually a linear geometrical structure. In enhancement to this, it consists of 2 bromine atoms.

Having the very same atoms in a molecule, they have actually an equal value of your electronegativity ie; the same influence on external inspection electrons.

As a result, both atoms have an equal distribution of charge.

Whereas in the instance of polar molecules, more electronegative atom benefit partial negative charge since it share a bigger proportion of external inspection electron pair.

In polar molecules, there exist two poles in a molecule (negative and also positive).

But in the instance of Br2 molecule, the fees on both atoms room the same making that a nonpolar molecule.

Lewis and Molecular structure of Br2

In the Br2 molecule, the lewis framework of Br2 is similar to that of F2, Cl2, etc.

The atoms favor Br, Cl, and also F belong to the 7th group of the routine table and also known as halogen elements.

The br2 is a diatomic molecule that has a complete of 14 valence electrons.

Both atom share one electron the each various other to finish their octet.

The diatomic molecule has a direct geometrical structure.

Below is the diagram for the molecular structure of the bromine diatomic molecule.

To know an ext about lewis structure, hybridization, and geometry of Br2 molecule, you have to refer come the write-up on lewis structure and geometry that Br2.


Factors affect polarity of a molecule

Electronegativity: the electronegativity of one atom is the strength of one atom to entice the external inspection electron pair. One atom having much more electronegativity attractive the external inspection electrons slightly much more towards it.

If there is a difference between the electronegativity of atom of a molecule, the molecule often tends to be polar.

The polarity of a molecule is directly proportional come the difference in between the electronegativity the atoms.

Dipole Moment: the is the term used to measure the polarity the a molecule. The is denoted by D (SI unit Debye). Mathematically, that is the product of the fee on atoms and distance in between them.

The polarity that a molecule is likewise directly proportional come its dipole moment.

D = Q * R

Geometrical Structure: The molecule that room symmetric in shape have actually their dipole moment as zero (nonpolar). Whereas those molecules that are asymmetric in shape have nonzero dipole minute (polar).

In the instance of linear-shaped molecules having actually the same electronegativity of both atoms are nonpolar in nature.

Properties of Br2

Bromine exists as a reddish-brown liquid and easily evaporable to kind gaseous fumes.The thickness of the bromine in liquid form is approximately 3.1028 g/cm3.The melting suggest of this compound is 265.8 K ​or −7.2 °C and also its boiling point is 332.0 K / 58.8 °C.The typical potential the this substance is 1.08 V.The first ionization energy of Br2 is 1142.7 kJ.mol -1.It has its suffocating and offensive smell.

Uses that Br2

It is widely offered in the agriculture industries for the ready of insecticides, pesticides.Bromine compounds have actually their good use as flame retardants. Lock are included to plastic furniture, electronic tools to do them much less flammable.The bromine compound favor Organobromides is used in the fire extinguisher.Silver bromide is a chemical the is widely supplied in movie photography.Bromine compounds choose 1,2-di-bromoethane which is an anti-knock certified dealer in the auto industry.


Bromine molecule is a liquid having actually a reddish-brown texture and easily evaporable to type gaseous fumes.

Br2 is a diatomic molecule having actually two bromine atoms is a linear-shaped structured compound. Having the same electronegativity that both atoms, both re-publishing an equal proportion of charge.

The atoms creating a covalent bond having actually equal electronegativity room nonpolar in nature.

Therefore, the Br2 molecule is a nonpolar molecule.
