WebBasically, Polar functional groups that are more exposed will elevate boiling points to a greater extent. (This applies for aldehydes, ketones and alcohols.) EXAMPLE - Among CH3CH2CH2CH2CH2 (OH) and CH3CH2CH (OH)CH2CH3, CH3CH2CH2CH2CH2 (OH) will have a greater boiling point than CH3CH2CH (OH)CH2CH3 since the latter is not exposed …

How do London dispersion forces affect boiling point? Socratic

WebAs a rule, larger molecules have higher boiling and melting points. Consider the boiling points of increasingly larger hydrocarbons. More carbons and hydrogens create a greater surface area possible for London forces, and thus higher boiling points.
