Bromine is a chemical compound v chemical formula Br2. The exists as a fuming red-brown colored liquid at room temperature. It easily gets evaporate to type same-color gas. In the periodic table, the is positioned at the third lightest halogen place. Many civilization have doubts around whether Br2 is polar or not. In this article, I will answer this question and also will cover its properties and also applications.

You are watching: Is br2 polar or nonpolar molecule

So, Is Br2 Polar or Nonpolar? Br2 (Bromine) is nonpolar because, in this molecule, both bromine atoms have the very same electronegativity because of which both atoms have actually equal fee distribution and also results in a net-zero dipole moment. That is direct in structure.

At room temperature, Bromine exists in a liquid state v reddish-brown texture. The is volatile in nature, conveniently evaporates in the form of a gas.

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

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


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

The Bromine is a very reactive substance and it does not occur openly in nature. The vapors of bromine gas are really toxic during inhalation. It can reason irritation in the throat and eyes.

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

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

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

Electronegativity of an atom is the strength with which it can lure the external inspection pair of electrons.

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

What room Polar and also Nonpolar Molecules?

The atom in the molecules are hosted by the shortcut forces. The varieties of the bond have the right to be ionic, covalent, metallic, and hydrogen bond.

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

The covalent bonds can have polarity depending upon various factors.

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

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

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

The bond created by two atoms is claimed to it is in nonpolar if they have actually equal electronegativity as result of which lock share an same proportion of charge.

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

Note: that is possible that a geometrically symmetric shame non-polar molecule deserve 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 actually a linear geometrical structure. In addition to this, it is composed of two bromine atoms.

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

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

Whereas in the situation of polar molecules, much more electronegative atom gains partial an unfavorable charge due to the fact that it shares a bigger proportion of external inspection electron pair.

In polar molecules, there exist 2 poles in a molecule (negative and also positive).

But in the situation of Br2 molecule, the dues on both atoms are the same making that a nonpolar molecule.

Lewis and Molecular framework of Br2

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

The atoms favor Br, Cl, and F belong to the 7th team 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 atoms share one electron that 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 more about lewis structure, hybridization, and also geometry the Br2 molecule, you need to refer come the article on lewis structure and geometry that Br2.


Factors affect polarity of a molecule

Electronegativity: the electronegativity of an atom is the toughness of an atom to tempt the bonded electron pair. One atom having much more electronegativity attracts the bonded electrons slightly more towards it.

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

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

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

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

D = Q * R

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

In the case of linear-shaped molecules having the very same electronegativity the both atoms room nonpolar in nature.

Properties that Br2

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

Uses of Br2

It is widely used in the agriculture industries because that the ready of insecticides, pesticides.Bromine compounds have their great use together flame retardants. Castle are added to plastic furniture, electronic tools to make them much less flammable.The bromine compound prefer Organobromides is used in the fire extinguisher.Silver bromide is a chemical that is widely supplied in movie photography.Bromine compounds prefer 1,2-di-bromoethane which is an anti-knock agent in the vehicle industry.


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

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

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

Therefore, the Br2 molecule is a nonpolar molecule.
