15. Some molecules that are covalently bonded do not have a difference in charge across the mol-
ecule. These molecules are referred to as nonpolar. What arrangement of electrons would result
in a nonpolar molecule?
16. Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances
interact with water?
17. What prediction would you make about why oil and water interact in the way described above?

Terms can be used once, more than once, or not at all. Reset Help Water molecules stay close to each other as a result of existence of hydrogen bonds. Collectively, hydrogen bonds hold the substance together, this phenomenon is called cohesion The clinging of one substance to another, which is called adhesion also plays a role. In this way, adhesion of water tırough hydrogen bonds to the molecules, which comprise the villi on the cat's tongue, helps counter the downward pull of gravity. As a result, such a phenomenon as adhesion helps drops of water stay whole and attached to each other. At the same time, cohesion allows drops to be transported…arrow_forward(b) Explain each of the following in terms of the properties of water.
