Chemistry - STEREO ISOMERISM Question with Solution | TestHub
List - I (Molecule) | List - II (Property) |
|---|---|
(P) | (1) It has no axis of symmetry |
(Q) | (2) Compound has even number of chiral centres. |
(R) | (3) Resolvable |
(S) | (4) Compound has odd number of chiral centres. |
| (5) Non resolvable |
Options:
Answer:
Solution:
P: Contains 6 chiral centers (even). It completely lacks symmetry (no axis) and is chiral, making it resolvable into enantiomers. Matches: (1), (2), (3)
Q: Contains 5 chiral centers (odd). Like P, it lacks any symmetry (no axis) and is chiral (resolvable). Matches: (1), (3), (4)
R: This fused cyclic structure has 4 chiral centers (even). It is entirely asymmetric (no axis) and is chiral (resolvable). Matches: (1), (2), (3)
S: This is meso-tartaric acid. It possesses 2 chiral centers (even). While it lacks a axis, a horizontal plane of symmetry makes it achiral and therefore non-resolvable. Matches: (1), (2), (5)
