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

Options

A. If both assertion and reson are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To solve the question regarding the assertion and reason about the polarity of cis and trans forms of alkenes, let's break it down step by step.

### Step 1: Understand the Assertion
The assertion states that the cis-form of an alkene is more polar than the trans-form.

**Explanation**: In the cis-form, the substituents (groups attached to the double bond) are on the same side. This arrangement leads to a net dipole moment because the individual dipole moments of the bonds do not cancel out.

### Step 2: Understand the Reason
The reason given states that in the trans-form, the groups are in opposite directions, which causes the dipole moments of the bonds to cancel each other out, making the trans-form almost non-polar.

**Explanation**: In the trans-form, the substituents are positioned opposite each other. This arrangement leads to the dipole moments of the bonds pointing in opposite directions, effectively canceling each other out, resulting in a net dipole moment that is close to zero.

### Step 3: Analyze the Relationship between Assertion and Reason
Both the assertion and reason are correct. The assertion correctly identifies that the cis-form is more polar due to the arrangement of groups, and the reason accurately explains why the trans-form is less polar due to the cancellation of dipole moments.

### Conclusion
Both the assertion and reason are true, and the reason correctly explains the assertion. Therefore, the answer is that both the assertion and the reason are correct.

### Final Answer
**Both the assertion and reason are correct, and the reason correctly explains the assertion.**
