Question

14) Which is true about the polarity of the substances in the graph?a. All are polar b. All are nonpolar c. Some are polar, some are nonpolar d. Unable to answer with info provided

Answer 1

c. Some are polar, some are nonpolar

Step-by-step explanation

Some substances on the graph are polar, for example NH3, in KNO3 the N-O binds are polar and some substances are non polar, e.g NaNO3.

If the electronegativity difference is 0.4 or less, the bond is polar. If the electronegativity is more than 0.4 but less than 1.8, the bond is non-polar. And if the difference is larger than 1.8, the substance is ionic.
