Match the following :
Column I (Compound) | Column II (Number of stereocenter) |
|---|---|
(A) | (P) 4 |
(B) | (Q) 1 |
(C) | (R) 3 |
(D) | (S) Shows G.I. |
Options:
Answer:
D
Solution:
Ans. A S; B P, S; C S; D R, S.
A (2-chlorocyclohexan-1-ol): C1 (OH) and C2 (Cl) are stereocentres (2 centres - not listed) and the molecule exists as cis/trans pairs, so it shows geometrical isomerism : S.
B (2,3,7-trimethylcycloheptan-1-ol, a seven-membered ring): C1, C2, C3 and C7 are stereocentres (4) and the molecule exists as cis/trans (diastereomeric) pairs : P, S.
C (2-chlorocyclopentan-1-ol): C1 and C2 are stereocentres (2 - not listed); cis/trans pairs exist : S.
D (1-bromo-2-chloro-3-methylcyclohexane): C1, C2 and C3 are stereocentres (3) and cis/trans diastereomeric pairs exist : R, S.
