Question

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

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
• B. If both Assertion and Reason are true but the reason is not the correct explanation of the Assertion
• C. If Assertion is true but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (A)

Boiling points of isomeric compounds depends on dipole-dipole interactions and cis-isomers have greater dipole moments (more polar) than trans-isomers (less polar).
