Question

Assertion : rans-Pent-2-ene is polar but transbut-2-ene is non-polar.

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

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (b) Both A and R are true but R is not correct explanation of A

Explanation:

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