HOCH3: 65°C
HOCH2CH2CH3: 98°C
HOCH2CH2CH2CH2CH3: 139°C
HOCH2CH2CH2CH2CH2CH2CH3: 176°C
Which of the following statements is correct for this set of compounds and supported by the data given? Select as many as applicable however points will be deducted for incorrect choices.
Select one or more:
The molecule with the strongest intermolecular forces is HOCH2CH2CH2CH2CH2CH2CH3
The boiling point of any of these alcohols should be higher than a non-polar hydrocarbon of similar molecular weight
The dominant effect behind this trend in boiling points is the strength of dispersion forces
The boiling point of any of these alcohols should be lower than a non-polar hydrocarbon of similar molecular weight
The dominant effect behind this trend in boiling points is the presence of hydrogen bonding
The molecule with the strongest intermolecular forces is HOCH3
