Question 3 • *26-27 CFISD TX-Chemistry A CR

When a polar molecule causes a charge redistribution in a nonpolar molecule, what are the molecules of the mixture most likely experiencing?

Answer
A
dipole-dipole interactions
B
nonpolar-nonpolar interactions
C
dipole-induced dipole interactions
D
induced dipole-induced dipole interactions

Explanation

A polar molecule has a permanent dipole, which can distort the electron cloud of a nearby nonpolar molecule and create a temporary, induced dipole. The attraction between the permanent dipole and the induced dipole is called a dipole-induced dipole interaction, so choice C is correct.
