Polyethylene Plastic Consists of Long Chains of Carbon Atoms, Each

question 7

Multiple Choice

Polyethylene plastic consists of long chains of carbon atoms, each of which is also bonded to hydrogens as shown below: Water forms beads when placed on a polyethylene surface. Why

• A) Water is nonpolar and polyethylene is nonpolar. Therefore there is very little interaction between these compounds. Accordingly, water beads are expected.
• B) Water is highly polar and polyethylene is nonpolar. Therefore there is very little interaction between these compounds. Accordingly, water beads are expected.
• C) Water is highly polar and polyethylene is polar. Therefore there is very little interaction between these compounds. Accordingly, water beads are expected.
• D) Water is highly polar and polyethylene is ionic. Therefore there is very little interaction between these compounds. Accordingly, water beads are expected.
• E) None of the above explains this example.
