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
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
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)
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
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
What is the consequence of large intermolecular forces in a substance?
High boiling point
High viscosity
High surface tension
All of the above
