Chemistry - STEREO ISOMERISM Question with Solution | TestHub
Different spatial arrangements of the atoms that result from rotation about a single bond are conformers. n-Butane has four conformers eclipsed, fully eclipsed, gauche and anti. The stability order of these conformers are as follows : Although anti is more stable than gauche but in some cases gauche is more stable than anti. Anti gauche Partial eclipsed Fully eclipsed
Number of possible conformations of n -butane is :
Options:
Answer:
Solution:
Question Explanation:
The question asks how many conformations are possible for n -butane due to rotation about its single bond.
Concept:
This question is based on Conformational isomerism.
Solution :
In n -butane, free rotation is possible around the single bond. Because this rotation is continuous, an infinite number of conformations are possible.
Final Answer: Option (D)
