Assertion : Lactic acid is optically active. Reason : Lactic acid has plane of symmetry.
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:
Lactic acid, molecule because it has a chiral carbon atom or asymmetric carbon atom and is therefore optically active. So, the option (3) is correct.

Which of the following contain plane of symmetry?
1 trans-1,3 dichloro cyclohexane
2 trans-1,2 dichloro cyclohexane
3 cis-1,2 dichloro cyclohexane
4 trans-1,3 cyclopentane
Explanation:
Meso compounds are characterized by an internal plane of symmetry that renders them achiral. Out of the given, cis-1,2-dichlorocyclohexane contain plane of symmetry.

Pick out the false statement.
1 Meso-tartaric acid is optically inactive.
2 Racemic lactic acid can be separated into active forms.
3 Butane-2,3-diol has only active form.
4 A molecule with n-different chiral centres can have \({{\rm{2}}^{\rm{n}}}\) isomers.
Explanation:
The number of optically active stereoisomers possible for butane-2, 3-diol is 2 . The meso compound is optically inacitve.
