Question

Which of the following isomers will have the highest boiling point? Explain the reason for your choice.

Answer 1

Solution :-

When the strength of the intermolecular force increases then the boiling point of the compounds also increases.

Out of the given three structures the isomer B that is cyclopentanol is the isomer that will have the highest boiling point beccause in the cyclopentanol -OH group is present which can form the hydrogen bonding. Hydrogen bonding is the strongest intermolecular forrce therefore it will lead to the higher boiling point of the cyclopentanol that is isomer 'B'
