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 correct, and reason is the correct explanation of the assertion.

B

If both assertion and reason are correct , but reason is not the correct explanation of the assertion.

C

If assertion is correct, but reason is incorrect .

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
a
cis-isomers have greater dipole moment . Greter
the dipole moment, higher is the boiling point
