- Q1
In the broadest sense, what was the Kinetic Molecular Theory designed to explain?
The types of crystalline solids
The types of intermolecular force
The behavior of matter
30s - Q2
What happens to the kinetic energy of particles when there is an increase in temperature?
increases
does not change
decreases
30s - Q3
Why are solids and liquids considered as condensed states?
They have lower densities.
They have smaller spaces between molecules compared to gas
Their particles vibrate at fix position
30s - Q4
Which of the following properties pertains to solid only?
They expand slightly when heated.
They diffuse extremely slow because the particles are tightly packed.
The kinetic energy is sufficient to overcome the attractive forces.
30s - Q530s
- Q6
What do you call the dipole-dipole attraction between hydrogen atom and electronegative elements F, O, and N?
Dipole-Dipole
Ion-Dipole
Hydrogen Bonding
30s - Q7
Which of the following among the intermolecular forces is considered the weakest?
Ion-Dipole
Hydrogen Bonding
London Dispersion
30s - Q8
Which of the following describes why the boiling point of CH4 (-161.6 °C) is much lower than that of HF (19.5 °C)?
The boiling point is higher in HF because the hydrogen bonding in HF is stronger than the attractive.
The boiling point is higher in HF because of the weaker dipole-dipole interactions in CH4.
The boiling point is higher in HF because of the weaker ion-dipole interactions in CH4
30s - Q9
Liquids with stronger intermolecular forces tend to have higher boiling point than those with weak intermolecular forces (London Dispersion<Dipole-Dipole<Hydrogen Bond).
Which of following compounds is correctly ranked with decreasing order of boiling point?
CH4> HCl>H2O
HCl>CH4>H2O
H2O> HCl>CH4
30s - Q10
What conclusion can be drawn from the circumstance in laundry washing where oil is removed from clothes when the nonpolar end of the detergent molecule attracts the non-polar oil molecules, while its polar end is attracted by the polar molecules of water?
Nonpolar compounds dissolve a polar compound.
Dissolution occurs in substances with similar polarities
Dissolution process takes place in any combination of compounds.
