Assertion : Boiling points of cis-isomers are higher than trans - isomers. Reason : Dipole moments of cis - isomers are higher than trans - isomers.

Answer»

If both assertion and REASON are true and the reason is the correct EXPLANATION of the assertion
If both assertion and reason are true and the reason is not the correct explanation of the assertion.
If assertion is true but reason is false.
If the assertion and reason both are false.

Solution :Boiling points of isomeric COMPOUNDS depend on dipole-dipole interactions and cis-isomers have GREATER dipole MOMENT (more polar) than trans-isomers (less polar).
