Molecules that differ in configuration CANNOT be:
a. stereoisomers
b. cis-trans isomers
c. chiral centers that are mirror images of each other
d. enantiomers
e. chiral centers that can be interchanged by rotation of a single bond
Homework Answers
Molecules that differ in configuration cannot be chiral centres that can be interchanged by rotation of a single bond
They can be stereoisomers because steroisomers are the molecules having different configuration in space. For eg - if one is R and another is S both of them can be stereoisomers and also both of them can be enantiomers.
Cis-trans are also a type of stereoisomers therefore the option is not correct
chiral centres that are mirror images of each other are also enantiomers hence this is also not correct.

3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms.

Stereochemistry is the study of the three‐dimensional structure
of molecules. The cis and trans isomers are forms
of stereoisomers, differing structurally only in
the location of the atoms of the molecule in three‐dimensional
space. Such stereoisomers can have different physical and chemical
properties. Stereochemistry is of particular interest to
biochemists because the reactivity and toxicity of molecules change
with their stereochemistry. Most body reactions are
stereospecific, meaning that receptor sites on
