Some Basic Principles Of Organic Chemistry Question 368
Question: Among the following the most stable compound is [AIIMS 2005]
Options:
A) $ cis-1,2-cyclohexanediol $
B) $ trans-1,2-cyclohexanediol $
C) $ cis-1,3-cyclohexanediol $
D) $ trans-1,3-cyclohexanediol $
Show Answer
Answer:
Correct Answer: D
Solution:
Trans configuration is more stable than cis configuration because in cis-configuration the H groups are thrown closely enough together to cause crowding or repulsion.
Again between 1,2-and 1,3-configurations, in 1-3, the OH groups are placed further apart to minimise the repulsion.
Hence, more stable is 1,3-configuration.
