Read the passage given below and answer the following questions:

The objects which are non-superimposable on their mirror image (like a pair of hands) are said to be chiral and this property is known as chirality. Chiral molecules are optically active, while the objects, which are, superimposable on their mirror images are called achiral. These molecules are optically inactive. The above test of molecular chirality can be applied to organic molecules by constructing models and its mirror images or by drawing three dimensional structures and attempting to superimpose them in our minds. There are other aids, however, that can assist us in recognising chiral molecules. One such aid is the presence of a single asymmetric carbon atom.

Q. In this questions a statement of assertion followed by a statement  of reason is given . Choose the correct answer out of the following  choices.
Assertion (A): A racemic mixture containing two enantiomers in equal proportions will have zero optical rotation.
Reason (R): This is because  the rotation due to one isomer will be cancelled by the rotation due to the other isomer.
  • a)
    Assertion and Reason both are correct statements and Reason is correct  explanation for Assertion.
  • b)
    Assertion and Reason both are correct statements but Reason is not correct explanation for Assertion.
  • c)
    Assertion is correct statement but reason is wrong statement.
  • d)
    Assertion is wrong statement but Reason is correct statement.
Correct answer is option 'A'. Can you explain this answer?

Explanation:

Assertion and Reason both are correct statements and Reason is correct explanation for Assertion.

- A racemic mixture containing two enantiomers in equal proportions will indeed have zero optical rotation.
- This is because the rotation due to one isomer will be cancelled out by the rotation due to the other isomer.
- Enantiomers are mirror images of each other and have opposite optical rotations.
- When present in equal amounts in a racemic mixture, the optical rotations cancel each other out, resulting in a net optical rotation of zero.
- Therefore, the statement that a racemic mixture will have zero optical rotation is true, and the reason provided explains why this is the case.

This explanation supports the assertion that a racemic mixture containing two enantiomers in equal proportions will have zero optical rotation.
