Problem 13: Isotopes

Carbon and oxygen have electronegativities of 2.5 and 3.5 respectively. Which atom would make a covalent bond with hydrogen (electronegativity= 2.1) that has a higher degree of polarity?

A.	carbon
	Incorrect. Carbon has a lower electronegativity (2.5) than oxygen (3.5), and has a lower affinity for electrons.
