Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Trans-Pent-2-ene is polar but trans-but-2 -ene is non-polar.
The probability of cis-isomer is more than trans-isomer , which are either non-polar or less polar.
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
The vector sum of all polar bonds in trans-pent-2-ene is not zero while in trans-but-2-ene it is zero.
Trans-but-2-ene has center of inversion. Thus it is symmetrical in nature.
