Bromine is a chemical compound with chemical formula Br2. It exists as a fuming red-brown colored fluid at room temperature. It readily gets evaporate to form same-color gas. In the routine table, it is positioned in ~ the third lightest halogen place. Many people have doubts around whether Br2 is polar or not. In this article, I will certainly answer this question and will sheathe its properties and also 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 the same electronegativity due to which both atoms have equal fee distribution and also results in a net-zero dipole moment. It is straight in structure.

At room temperature, Bromine exist in a fluid state v reddish-brown texture. That is volatile in nature, readily evaporates in the form of a gas.

It is classified as a halogen compound. Couple of examples of together compounds space chlorine, fluorine.

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


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

The Bromine is a highly reactive substance and also it does no occur easily in nature. The vapors that bromine gas are really toxic during inhalation. The can reason irritation in the throat and also eyes.

If we talk around the chemical structure of Bromine molecule, the is a linear-shaped molecule that consists of two bromine atom at both ends covalently bonded.

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

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

Electronegativity of one atom is the toughness with which the can lure the bonded pair the electrons.

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

What space Polar and also Nonpolar Molecules?

The atoms in the molecules are held by the shortcut forces. The species of the bond have the right to be ionic, covalent, metallic, and also hydrogen bond.

The covalent and also ionic have much higher strength as compared to other types of bonds.

The covalent bonds can have polarity depending on various factors.

Polar Molecules: These space the molecule that have actually atoms covalently bonded and have uneven charge distribution on them.

The covalent bond between two atoms is claimed to it is in polar if both atoms differ in their electronegativity due to which castle share an unlike proportion the charge.These molecules have non zero dipole moment. Few examples of such molecules space IF5, HO2, etc. Girlfriend can inspect out the factor for the polarity the IF5.

Non-Polar Molecule: These space the molecule that have covalently external inspection atoms having equal circulation of fee on them.

The bond developed by two atoms is claimed to it is in nonpolar if they have equal electronegativity due to which they share an equal proportion of charge.

Examples of such molecules are Hexane, CO2, etc. Girlfriend can examine out the factor for the non-polarity that Hexane.

Note: it is possible that a geometrically symmetric shaped 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 every other leading to a nonpolar molecule.

Why is Br2 a Nonpolar Molecule?

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

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

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

Whereas in the case of polar molecules, an ext electronegative atom gains partial an unfavorable charge since it shares a larger proportion of external inspection electron pair.

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

But in the case of Br2 molecule, the fees on both atoms are the very same making it a nonpolar molecule.

Lewis and Molecular framework of Br2

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

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

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

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

The diatomic molecule has actually a linear geometrical structure.

Below is the diagram because that the molecular structure of the bromine diatomic molecule.

To know more about lewis structure, hybridization, and also geometry of Br2 molecule, you must refer to the post on lewis structure and also geometry the Br2.


Factors affecting polarity that a molecule

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

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

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

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

The polarity that a molecule is additionally directly proportional to its dipole moment.

D = Q * R

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

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

Properties that Br2

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

Uses that Br2

It is widely provided in the agriculture industries because that the preparation of insecticides, pesticides.Bromine compounds have their an excellent use together flame retardants. Lock are added to plastic furniture, electronic tools to do them much less flammable.The bromine compound favor Organobromides is provided in the fire extinguisher.Silver bromide is a chemical the is widely used in movie photography.Bromine compounds favor 1,2-di-bromoethane which is an anti-knock certified dealer in the car industry.


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

Br2 is a diatomic molecule having actually two bromine atom is a linear-shaped structured compound. Having the same electronegativity the both atoms, both re-publishing 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.
