How do two structural isomers differ from each other?
Expert Solution & Answer
To determine
To state:
The way in which two structural isomers are different from each other.
Answer to Problem 1RCC
Solution:
Structural isomers have same number of atoms but they differ in the connectivity of different atoms present in a molecular formula.
Explanation of Solution
Structural isomer is a term in which molecular formula is same. Connectivity of the different atoms present in a molecule changes. Due to different connectivity of the atoms, physical properties of structural isomers also changes. More than two structural isomers are also possible, depending upon the given molecular formula. Structural isomers of pentane with molecular formula C5H12 are shown below.

Indicate the relationship between the two structures in the pair. Are they chair conformations of the same
molecule? If so, are they conformational diastereomers, conformational enantiomers, or identical? If they are
not conformations of the same molecule, what is their stereochemical relationship?
