Plastic wrap is made of nonpolar molecules and is able to stick well to polar surfaces,such as glass,by way of dipole/induced dipole molecular attractions.How is it that plastic wrap also sticks to itself so well?
A)by way of dipole-dipole molecular attractions
B)by way of dipole-induced dipole molecular attractions
C)Ions are formed as the plastic rubs against itself.
D)by way of induced dipole-induced dipole molecular attractions

Quizplus · Accepted Answer

Plastic wrap is made of nonpolar molecules, which are unable to form dipole-dipole or ion-dipole attractions. However, they can form temporary induced dipoles through the movement of their electrons. When plastic wrap is pressed against itself, the induced dipoles of one side can interact with the induced dipoles of the other side, creating a stronger adhesive force through induced dipole-induced dipole attractions. Therefore, option D is the correct answer.
