Quiz | Liquids and Solids

1

What type of intermolecular forces are due to the attraction between temporary dipoles and their induced temporary dipoles?

Ionic bond

Hydrogen bond

London dispersion

Van der Walls interaction

London dispersion forces are electrostatic interactions that occur between two nonpolar molecules

2

Which of the following compounds cannot exhibit hydrogen bonding?

HF

CH4

H2O

CH3NH2

CH4 has neither a hydrogen atom bonded to N, O or F nor an electronegative atom having a lone pair of electrons ⇒ This molecule cannot exhibit a hydrogen bond

3

What is the normal boiling point of a liquid?

The temperature at which the liquid will usually boil

The temperature at which the vapor pressure = 1 atm

The only temperature at which there can be equilibrium between liquid and gas

The temperature at which liquid and gas become indistinguishable from each other

The normal boiling point is the temperature at which vapor pressure = atmospheric pressure (1 atm)

4

Where on a phase diagram can you find conditions under which only one phase exists?

On a line

At the triple point

At the critical point

In an area bounded by lines

5

What is the property responsible for the ‘beading up’ of water?

Viscosity

Vapor pressure

Surface tension

Hydrogen bonding

Surface tension is the energy required to increase the surface area of a liquid and is therefore responsible for the 'beading up' of water

6

What is the consequence of large intermolecular forces in a substance?

High boiling point

High viscosity

High surface tension

All of the above
