Assertion : trans-Pent-2-ene is polar but trans- but-2-ene is non-polar. Reason : The polarity of cis-isomer is more than trans-isomer, which are either non-polar or less polar.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

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

Step-by-step solution

The vector sum of all polar bonds in trans-pent-2-ene is not zero while in trans-but-2-ene it is zero.
