The bond that joins a carbon atom to each hydrogen atom is a covalent single bond. Specifically, it is a carbon–hydrogen (C–H) covalent bond where carbon shares one of its valence electrons with hydrogen, completing the outer electron shells of both atoms and making the bond stable

. This C–H bond is generally considered a nonpolar covalent bond because the electronegativity difference between carbon (2.55) and hydrogen (2.2) is small (about 0.35), resulting in an almost equal sharing of electrons

. In summary:

• The bond type is a single covalent bond.
• It is typically nonpolar due to the small difference in electronegativity.
• Carbon shares one electron with each hydrogen atom, forming a stable bond in organic molecules
