Chlorine is a chemical compound v the chemical formula Cl2. It is thought about as a second lightest halogen. In ~ room temperature, it exists together a pale yellowish-green gas. Plenty of students may have actually a doubt regarding whether Cl2 is polar or not. In this article, we will discuss it and also will also cover its properties and also applications.

So, Is Cl2 Polar or Nonpolar? Cl2 (Chlorine) is nonpolar in nature because of its straight symmetrical shape and it consists of two chlorine atoms having actually equal electronegativity. As a result, both atoms have equal charge distribution on them, and the molecule outcomes in zero dipole moment that renders the chlorine molecule nonpolar.

Chlorine is a highly reactive element and also exists in the gas state in ~ room temperature. It has its texture together greenish-yellow.

This compound is a strong oxidizing agent and has the highest electron affinity among other elements.

In the routine table, the Chlorine facet is placed at the net in period 3 and group 17.

As it is extremely reactive, that is current in the earth’s crust in the type of ionic chloride compounds. After fluorine, Chlorine is the second most plentiful halogen current in nature.

Commercially, chlorine is extracted from the brine by the electrolysis process. That was very first synthesized in the year 1630 but was not claimed as critical element.

If us talk about the chemical composition of the chlorine molecule, it is composed of two atoms the chlorine fastened by a covalent bond.

Its molecule mass is calculated as

Mol. Mass of Cl2 = 2 * 35.45 (at fixed of Cl) = 70.906 g/mol.

The geometry the the chlorine gas molecule is linear as the is a diatomic molecule. The diatomic molecules deserve to only be external inspection linearly.

Both atoms have equal electronegative value. Therefore, both atoms have an equal proportion of external inspection electrons.

The electronegativity that the chlorine atom is 3.16.

Due to equal charge circulation on both atoms, over there exists no polarity across the molecule.

Below is the photo of the molecular framework (linear) the the Chlorine molecule.


Polar and also Nonpolar Molecules?

The molecule are held by interatomic pressures like covalent, ionic, hydrogen bond, and metallic bond. Out of these, covalent and also ionic bonds are the strongest.

The covalent bonds deserve to be polar and nonpolar that counts upon various determinants like electronegativity, geometrical shape, and also dipole moment of the whole molecule.

Polar Molecules: The molecules that have actually some magnitude of net dipole minute (non zero) are known as a polar molecule. These molecules have unequal circulation of charges on its atoms.

The covalent shortcut formed in between two atoms is claimed to be polar if both atom share a various proportion that charge. Instances of together molecules room H2O, NH3. Friend can check out the factor for the polarity of NH3.

There exist two poles in a molecule ie; positive and also negative.

Nonpolar Molecules: These are the molecule that have actually zero dipole moment. The atoms in such molecules have actually an equal distribution of charge.

The atoms combine covalently to kind a nonpolar molecule if the atoms share an same proportion the charge. Over there exist no two poles in such a molecule.

Examples of together molecules space CCl4, Br2. Girlfriend can inspect out the factor for the non-polarity the Br2.

Why is Cl2 a Nonpolar Molecule?

The chlorine gas molecule consists of 2 chlorine atoms. Both atoms have equal electronegativity ie; both have equal influence on the bonded pair the electrons.

Electronegativity is the term that depicts the strength of one atom to lure the external inspection pair that electrons in the direction of it.

The chlorine molecule is a diatomic molecule and also therefore linearly connected.

As a result, Both Cl atom share the very same amount of charge as result of which no polarity rises across it.

And the dipole moment likewise turns out to it is in zero.

Factors that influence the polarity the a molecule

Electronegativity: The ax electronegativity is the most vital parameter to check whether a molecule is polar or not.

If 2 atoms creating a covalent bond different in your electronegativity, the bond created tends to be polar in nature.Due come the difference in between the electronegativity that both atoms, they have an unequal re-publishing of the charge.

Dipole moment: The dipole the a molecule is the measure up of that is polarity. The polarity of a molecule is directly proportional to its dipole moment.

The dipole moment of a molecule is the product of charges and also distance in between them. The is a vector quantity ie; it has actually magnitude and also direction.

D = Q * R

Geometrical Shape: The shape of a molecule likewise decides the polar or nonpolar nature the a molecule.

The molecule that room symmetrical in shape are nonpolar in nature whereas the molecule that space asymmetric room polar.

Note: it is essential to store in mind the a nonpolar molecule can have polar bonds within it yet due to the symmetrical framework of the molecule, the polarity that those bonds gets canceled through each other.

Properties that Cl2

Chlorine gas exists together a pale yellowish-green gas at room temperature.It has actually a suffocating smell.It is a very reactive gas.The molecule mass the Cl2 is 35.453 g.mol -1.At the temperature the 20 °C, the density of this gas is 3.21*10 -3 -3. Ie; two and also one-half time as heavy as airIt is conveniently soluble in water. As such mixed in water for the objective of chlorination.The melting allude of chlorine is -101 °C and also its boiling allude is -34.6 °C.The conventional potential that Chlorine is – 1.36 V.Its first ionization value is 1255.7 kJ.mol -1.

Uses the Cl2

It is majorly provided for treating drinking water by the procedure known together chlorination. Regional authorities include the required amount the chlorine to disinfect the water from bacter impurities.It is additionally used in sectors for the manufacturing of dyes, paper, and paints.It is also used in the health treatment industries fr production of medicine.It is offered to prepare antiseptics.It is also included to the swimming swimming pool for disinfecting the pool water.


The chlorine molecule is a diatomic molecule consisting of two chlorine atoms. Both atoms have actually equal electronegativity. It way both share an same proportion the charge.

As a result, the molecule developed by two chlorine atom is nonpolar.
