प्रश्न
Assertion (A): Trans [CrCl2(ox)2]3− shows optical isomerism.
Reason (R): Optical isomerism is common in octahedral complexes involving didentate ligands.
पर्याय
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
Assertion (A) is true, but Reason (R) is false.
Assertion (A) is false, but Reason (R) is true.
उत्तर
Assertion (A) is false, but Reason (R) is true.
Explanation:
Optical isomers are mirror images that cannot be superimposed on each other, hence, cis[CrCl2(OX)2]3− is chiral, and trans[CrCl2(OX)2]3− is symmetrical and not optically active.
