Problem 14: Electronegativity

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.
B.	oxygen.
C.	both carbon and oxygen since covalent bonds always have the same polarity..
D.	neither, only ionic bonds produce a polar or charge separation effect..
