Order of polarity of HCL CO2 H20 HF
Order of polarity of HCL CO2 H20 HF
Solution and Explanation
The order of polarity, from least polar to most polar, among the given molecules is as follows:
- CO2 (Carbon dioxide) - Nonpolar molecule due to its linear arrangement and the symmetry of its bonds.
- HCl (Hydrogen chloride) - Polar molecule due to the electronegativity difference between hydrogen and chlorine.
- H2O (Water) - Highly polar molecule due to the bent molecular geometry and the significant electronegativity difference between hydrogen and oxygen.
- HF (Hydrogen fluoride) - Highly polar molecule due to the strong electronegativity difference between hydrogen and fluorine, similar to water
Order of increasing polarity is CO2 < HCl < H2O < HF

Concepts Used:
Chemical Bonding and Molecular Structure
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
Types of Chemical Bonds:
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
- Ionic Bonds - Ionic bonding is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another.
- Covalent Bonds - Compounds that contain carbon commonly exhibit this type of chemical bonding.
- Hydrogen Bonds - It is a type of polar covalent bonding between oxygen and hydrogen wherein the hydrogen develops a partial positive charge
- Polar Bonds - In Polar Covalent chemical bonding, electrons are shared unequally since the more electronegative atom pulls the electron pair closer to itself and away from the less electronegative atom.
Factors Affecting Bond Enthalpy in Chemical Bonding:
- Size of the Atom
- Multiplicity of Bonds
- Number of Lone Pair of Electrons Present
- Bond Angle
