Assertion:- Trihydroxyglutaric acid exists in four
stereoisomeric forms, two of which are optically active while the other two are meso-forms.
Reason :- It contains two asymmetric and one pseudo-asymmetric carbon atom.
stereoisomeric forms, two of which are optically active while the other two are meso-forms.
Reason :- It contains two asymmetric and one pseudo-asymmetric carbon atom.
View answer and explanation
Correct option: A
If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
Option A (If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion) is correct because the presence of two asymmetric carbons and one pseudo-asymmetric carbon in trihydroxyglutaric acid leads to the existence of four stereoisomers, including two meso forms and two optically active forms.

Assertion (A): The compounds that have the same constitution and sequence of covalent bonds but differ in relative positions of their atoms or groups in space are called stereoisomers.
