Multiple choice

Assertion: CHBr=CHCl exhibits geometrical isomerism but CH2Br-CH2Cl does not. Reason: Presence of C=C is one of the conditions of geometrical isomerism.

  2. Both A and R are true but R is NOT the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

  5. Both A and R are false.

C Correct answer
Explanation

CHBr=CHCl exhibits geometrical isomerism but CH2Br-CH2Cl does not, because the molecule may or may not contain a double bond, only restricted rotation about a bond give rise to geometrical isomerism. Thus, this option is correct.
