Intermolecular Forces - Quiz Quiz

Question 1

ICl has a higher boiling point than Br sub 2 What is the best explanation for this?

Revolt · Accepted Answer

D: ICl experiences dipole-dipole interactions.

Question 2

Which statement best explains why water has a higher boiling point than ethane?

Revolt · Accepted Answer

C: Ethane molecules have no hydrogen bonds and need less energy to separate.

Question 3

Are hydrogen bonds formed between all molecules?

Revolt · Accepted Answer

C: No because hydrogen can only form these bonds with highly electronegative atoms.

Question 4

Hydrogen bonding is necessary for

Revolt · Accepted Answer

B: forming double-stranded DNA molecules.

Question 5

Which statement about van der Waals forces is true?

Revolt · Accepted Answer

A: When the forces are weaker, a substance will have higher volatility.

Question 6

Which interaction produces dispersive forces by creating temporary dipoles that induce dipoles in other molecules?

Revolt · Accepted Answer

B: induced dipole-induced dipole

Question 7

Substances X and Y are both nonpolar. If the volatility of X is higher than that of Y, what is the best explanation?

Revolt · Accepted Answer

D: Y’s molecules experience stronger London dispersion forces than X’s molecules.

Question 8

Which forces can be classified as intramolecular?

Revolt · Accepted Answer

A: covalent bonds

Question 9

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

Revolt · Accepted Answer

C: dipole-induced dipole interactions

Question 10

van der Waals forces can best be described as the attractive or repulsive forces that are formed

Revolt · Accepted Answer

B: by a random, short-lived redistribution of electrons.
