Assertion : cis-From of but-2-ene is found to be more polar than the trans-form.
Reason : Since the groups are in opposite directions, the dipole moments of bonds cancel each other making trans form almost non-polar.

Question Explanation:

Reasoning the polarity difference between cis and trans but-2-ene.

Concept:

Dipole Moment and Molecular Symmetry.

Solution:

The assertion is true: cis-but-2-ene is polar whereas trans-but-2-ene is nearly non-polar. The reason correctly explains this: in the trans-form, methyl groups are in opposite directions, causing their bond dipole moments to cancel out.
