Homework Answers
The correct answer is option D that is Ⅲ < Ⅰ < Ⅳ < Ⅱ
EXPLANATION:
The boiling point of the compound depend on the relative strength of the intermolecular forces present .
The order of the kind of intermolecular forces is
ionic bond > hydrogen bond > dipole dipole > vander waals dispersion
Now , in CH3COCH3 dipole dipole interaction is present since C=O bond is polar
In KCl ionic interaction is peesent
In Kr dispersion forces are present
In CH3CH(OH)CH3 hydrogen bonding is present .
THus the order of increasing boiling point will be
Kr < CH3COCH3 < CH3CH(OH)CH3 < KCl
