Chlorine is a chemical compound with the chemistry formula Cl2. The is considered as a second lightest halogen. At room temperature, the exists together a pale yellowish-green gas. Numerous students may have actually a doubt concerning whether Cl2 is polar or not. In this article, us will comment on it and will also cover that properties and also applications.

You are watching: Cl-cl polar or nonpolar

So, Is Cl2 Polar or Nonpolar? Cl2 (Chlorine) is nonpolar in nature since of its direct symmetrical shape and also it is composed of 2 chlorine atoms having actually equal electronegativity. Together a result, both atoms have actually equal charge distribution on them, and also the molecule results in zero dipole minute that provides the chlorine molecule nonpolar.

Chlorine is a extremely reactive element and exists in the gaseous state in ~ room temperature. It has actually its texture as greenish-yellow.

This compound is a solid oxidizing agent and also has the highest possible electron affinity amongst other elements.

In the routine table, the Chlorine aspect is put at the network in duration 3 and group 17.

As it is extremely reactive, the is current in the earth crust in the type of ionic chloride compounds. After ~ fluorine, Chlorine is the 2nd most numerous halogen present in nature.

Commercially, chlorine is extract from the brine through the electrolysis process. That was first synthesized in the year 1630 yet was not claimed as crucial element.

If we talk around the chemical composition the the chlorine molecule, it is composed of 2 atoms the chlorine fastened by a covalent bond.

Its molecule mass is calculation as

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

The geometry the the chlorine gas molecule is direct as that is a diatomic molecule. The diatomic molecules have the right to only be external inspection linearly.

Both atoms have equal electronegative value. Therefore, both atoms have actually an equal proportion of bonded electrons.

The electronegativity the the chlorine atom is 3.16.

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

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


Polar and Nonpolar Molecules?

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

The covalent bonds have the right to be polar and nonpolar that counts upon various factors like electronegativity, geometrical shape, and dipole moment of the entire molecule.

Polar Molecules: The molecule that have actually some size of net dipole moment (non zero) are well-known as a polar molecule. These molecules have actually unequal distribution of fees on that is atoms.

The covalent bond formed between two atom is claimed to be polar if both atom share a different proportion of charge. Examples of together molecules space H2O, NH3. Girlfriend can inspect out the factor for the polarity that NH3.

There exist 2 poles in a molecule ie; positive and negative.

Nonpolar Molecules: These are the molecule that have zero dipole moment. The atom in together molecules have an equal circulation of charge.

The atoms integrate covalently to form a nonpolar molecule if the atom share an equal proportion of charge. There exist no 2 poles in such a molecule.

Examples of together molecules room CCl4, Br2. Girlfriend can examine 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 actually equal electronegativity ie; both have actually equal affect on the external inspection pair the electrons.

Electronegativity is the term that depicts the strength of an atom to tempt the external inspection pair of electrons towards it.

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

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

And its dipole moment additionally turns the end to it is in zero.

for much better understanding, examine out the video.

Factors that affect the polarity of a molecule

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

If 2 atoms creating a covalent bond differ in your electronegativity, the bond created tends to it is in polar in nature.Due to the difference 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 polarity. The polarity that a molecule is straight proportional come its dipole moment.

The dipole minute of a molecule is the product of charges and distance between them. That is a vector amount ie; it has actually magnitude and direction.

D = Q * R

Geometrical Shape: The form of a molecule also decides the polar or nonpolar nature the a molecule.

The molecules that space symmetrical in form are nonpolar in nature vice versa, the molecule that room asymmetric space polar.

Note: the is essential to save in mind the a nonpolar molecule deserve to have polar bonds in ~ it but due to the symmetrical framework of the molecule, the polarity of those bonds it s okay canceled v each other.

Properties that Cl2

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

Uses of Cl2

It is majorly supplied for treating drinking water by the procedure known as chlorination. Neighborhood authorities include the compelled amount that chlorine to disinfect the water from bacter impurities.It is likewise used in markets for the manufacturing of dyes, paper, and paints.It is likewise used in the health treatment industries fr production of medicine.It is supplied to prepare antiseptics.It is also added to the swimming pool for disinfecting the swimming pool water.


The chlorine molecule is a diatomic molecule consists of 2 chlorine atoms. Both atoms have equal electronegativity. It way both re-superstructure an same proportion that charge.

As a result, the molecule created by 2 chlorine atoms is nonpolar.
