* Hydrogen (H): 2.20
* Carbon (C): 2.55
What is electronegativity?
Electronegativity is a measure of an atom's ability to attract electrons towards itself when it's part of a chemical bond.
* Higher electronegativity: Means an atom has a stronger pull on shared electrons.
* Lower electronegativity: Means an atom has a weaker pull on shared electrons.
Implications for H-C bonds:
The difference in electronegativity between carbon and hydrogen is relatively small. This means that the C-H bond is considered nonpolar covalent. The electrons are shared fairly equally between the two atoms.
