Carbon and hydrogen make up many biologically important molecules.Carbon has an electronegativity of 2.55 while hydrogen has an electronegativity of 2.0.On the scale of electronegativity from zero (0)to four (4),the carbon and hydrogens shown here have just formed

Question

Quizplus · Accepted Answer

The difference in electronegativity between carbon and hydrogen is only 0.55 (2.55-2.0), which is below the threshold of 0.5 for a polar covalent bond. Therefore, the bond between carbon and hydrogen is considered nonpolar.
