Chemical Bond Polarity Calculator

25 comments

Chemical Bond Polarity Calculator helps determine whether a covalent bond between two atoms is polar or non-polar. It uses the difference in electronegativity values to identify the type of bond formed. This tool is useful for chemistry students and professionals to understand electron sharing behavior in molecules and the tendency of atoms to attract electrons.

Electronegativity Difference Formula

Formula
$$\Delta EN = | EN_1 – EN_2 |$$

Where:

  • $$EN_1$$ and $$EN_2$$ are the electronegativities of the two atoms
  • $$\Delta EN$$ is the absolute difference, which determines the bond type:
    • $$\Delta EN < 0.4$$: Non-polar covalent bond
    • $$0.4 \leq \Delta EN \leq 1.7$$: Polar covalent bond
    • $$\Delta EN > 1.7$$: Ionic bond (not covalent, shown for reference)


Bond polarity describes the distribution of electron density in a chemical bond. This calculator is especially useful in identifying the type of bond formed in a diatomic molecule. Users can select two chemical elements, and the calculator fetches their standard electronegativity values to calculate the difference. The result explains if the bond is polar or non-polar, helping in molecular geometry and reactivity predictions. This is crucial in fields like organic chemistry, pharmacology, and material science.

    c2h6 says polar but it 100% should be non polar the EN difference is 0.35 which is under 0.5 so idk

    This is the range:
    Non-polar covalent: 0.0βˆ’0.4
    Polar covalent: 0.5βˆ’1.8
    Ionic compound: 1.8+

    Li2Be is not polar its ionic , this says its polar covalent, g1 alkalines and g2 alkali metals ( except Be ) always make ionic compounds , you guys need to correct such things
