(a)
Interpretation:
The compound that exhibits weaker intermolecular forces has to be given.
Concept introduction:
London Dispersion forces:
London dispersion forces are weak interactions due to the temporary changes in electron density in a molecule. All covalent compound exhibits London dispersion forces. These intermolecular forces are the only intermolecular forces present in nonpolar compounds.
Hydrogen Bonding:
A
Dipole-dipole interactions:
Dipole–dipole interactions are electrostatic interactions between molecules which have permanent dipoles. This interaction is stronger than the London forces but is weaker than ion-ion interaction because only partial charges are involved positive end of a polar molecule will attract the negative end of the other molecule and influence its position
(b)
Interpretation:
The compound, which has higher boiling point, has to be given.
(c)
Interpretation:
The compound, which has higher melting point, has to be given.

- What is the intermolecular force between carbon tetrachloride and water. What about carbon tetrachloride and cyclohexane? Is carbon tetrachloride more soluble in water or cyclohexane?arrow_forwardPropane boils at -42 degree Celsius, ethanal boils at 20.8 degree Celsius and ethanol boils at 78.3 degree Celsius. Although their molecular masses are very similar, their boiling points are very different, explain why?arrow_forwardArrange the given compounds in the picture (in order of increasing boiling point). 1 is the lowest boiling point, 5 is the highest boiling point.arrow_forward
- Based on what you know about the boiling points of Methyl-benzene, 2-Acetyltoluene, 4-Acetyltoluene in which are intermolecular forces strongest? Why? Which intermolecular forces are present in each?arrow_forwardFats and oils are an essential part of our diets. much of their molecular structure consists of long hydrocarbon chains. a.
