Assertion(A): Propadiene is optically active.
Reason(R): Propadiene has a plane of symmetry.
  • a)
    Both Assertion and Reason are true and Reason is the correct explanation of assertion.
  • b)
    Both Assertion and Reason are true but Reason is not the correct explanation of assertion.
  • c)
    Assertion is true but Reason is false.

Assertion and Reason Type Question on Organic Chemistry

Explanation:

Propadiene is a molecule having two carbon atoms and two double bonds.

It is linear and has a plane of symmetry.

Assertion: Propadiene is optically active.

Reason: Propadiene has a plane of symmetry.

Option (D) Both Assertion and Reason are false:

Propadiene is an example of a molecule that has an internal plane of symmetry and is therefore not optically active.

It is achiral, which means it is superimposable on its mirror image.

Therefore, both the Assertion and Reason are false because propadiene does not have optical activity even though it has a plane of symmetry.

Conclusion:

The correct answer is option (D) Both Assertion and Reason are false.
