Bromine is a chemical compound with chemical formula Br2. It exists together a fuming red-brown colored liquid at room temperature. It conveniently gets evaporate to kind same-color gas. In the regular table, it is positioned at the 3rd lightest halogen place. Many people have doubts about whether Br2 is polar or not. In this article, I will certainly answer this question and will cover its properties and applications.

You are watching: Is br-br polar or nonpolar

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

At room temperature, Bromine exist in a liquid state with reddish-brown texture. That is volatile in nature, easily evaporates in the type 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 actually one valence electron in that outermost electronic configuration.


The chemistry composition the the bromine molecule includes two atoms of bromine and also forms the molecular weight equals to 79.904 g/mol.

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

If us talk about the chemical framework of Bromine molecule, the is a linear-shaped molecule that has two bromine atoms at both ends 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 the very same electronegativity, therefore, both of these atoms have equal influence on the external inspection pair that electrons.

Electronegativity of an atom is the stamin with which that can entice the bonded pair of electrons.

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

What are Polar and also Nonpolar Molecules?

The atom in the molecules are hosted by the shortcut forces. The species of the bond can be ionic, covalent, metallic, and also hydrogen bond.

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

The covalent bonds deserve to have polarity depending on various factors.

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

The covalent bond between two atom is said to it is in polar if both atom differ in their electronegativity as result of which lock share an unlike proportion that charge.These molecules have non zero dipole moment. Couple of examples of together molecules space IF5, HO2, etc. Friend can examine out the factor for the polarity of IF5.

Non-Polar Molecule: These space the molecule that have covalently bonded atoms having actually equal circulation of charge on them.

The bond developed by 2 atoms is said to be nonpolar if they have equal electronegativity due to which lock share an equal proportion the charge.

Examples of together molecules are Hexane, CO2, etc. Friend can examine out the factor for the non-polarity of Hexane.

Note: it is possible that a geometrically symmetric shame non-polar molecule can have a polar bond within it. However due to its symmetric shape, the polarity it s okay canceled by each other leading to a nonpolar molecule.

Why is Br2 a Nonpolar Molecule?

The bromine molecule has a straight geometrical structure. In enhancement to this, it is composed of 2 bromine atoms.

Having the very same atoms in a molecule, they have an equal worth of their electronegativity ie; the same affect on bonded electrons.

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

Whereas in the case of polar molecules, an ext electronegative atom profit partial negative charge since it share a bigger proportion of bonded electron pair.

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

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

Lewis and Molecular structure of Br2

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

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

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

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

The diatomic molecule has a straight geometrical structure.

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

To know an ext about lewis structure, hybridization, and also geometry of Br2 molecule, you should refer come the post on lewis structure and geometry of Br2.


Factors influence polarity of a molecule

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

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

The polarity that a molecule is straight proportional come the difference between the electronegativity that atoms.

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

The polarity that a molecule is also directly proportional to 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 molecule that room asymmetric in shape have actually nonzero dipole minute (polar).

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

Properties of Br2

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

Uses the Br2

It is widely supplied in the agriculture industries for the ready of insecticides, pesticides.Bromine compounds have their great use together flame retardants. Castle are added to plastic furniture, electronic gadgets to do them much less flammable.The bromine compound choose Organobromides is used in the fire extinguisher.Silver bromide is a chemical the is widely used in movie photography.Bromine compounds favor 1,2-di-bromoethane i m sorry is an anti-knock agent in the vehicle 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 atom is a linear-shaped structured compound. Having the exact same electronegativity of both atoms, both share an same 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.
