Read the Assertion and Reason carefully to mark the correct option out of the options given below. Assertion : Cis form of alkene is found to be more polar than the trans form. Reason : Dipole moment of trans isomer of 2-butene is zero.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Dipole moment is a vector quantity and for a molecule not dipole moment is the sum of all bond dipoles, therefore dipole moment of cis is higher than trans form. So, the correct option is (1).

Assertion : \(\mathrm{CHBr}=\mathrm{CHCl}\) exhibits geometrical isomerism but \(\mathrm{CH}_{2} \mathrm{Br}-\mathrm{CH}_{2} \mathrm{Cl}\) does not. Reason : Presence of \(\mathrm{C}=\mathrm{C}\) is one of the conditions of geometrical isomerism.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The molecule may or may not contain a double bond; only restricted rotation about a bond gives rise to geometrical isomerism. Moreover, the groups across the carbon atoms with restricted rotation should be bonded to different atoms or groups. So, option (3) is correct.
