What is the electronegativity difference in CH4?

C has an electronegativity of 2.55 and H has an electronegativity of 2.2, giving an EN difference of 0.35. This classifies the bond as nonpolar covalent.

Is Methane (CH4) ionic or covalent?

Methane has nearly nonpolar C-H bonds. Carbon (EN 2.55) and hydrogen (EN 2.20) have such similar electronegativities that electrons are shared almost equally.

Overview

Methane is the simplest organic molecule. Four C-H bonds connect carbon to hydrogen atoms in a tetrahedral arrangement.

Electronegativity Analysis

Carbon has an EN of 2.55, hydrogen has 2.20. The difference of only 0.35 is below the 0.4 threshold, making these bonds essentially nonpolar.

Electron Behavior

Electrons are shared nearly equally between C and H. No significant partial charges develop on either atom.

Physical Properties

Nonpolar covalent molecules have low melting points, do not conduct electricity, and are insoluble in water but dissolve in nonpolar solvents like hexane.
