Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Stereoisomers that are non-superimposable mirror images of each other are known as:
A
anomers.
B
cis-trans isomers.
C
diastereoisomers.
D
enantiomers.
E
geometric isomers.
Explanation: 

Detailed explanation-1: -Enantiomers are defined as a pair of stereoisomers that are non-superimposable mirror images of one another. This means they are molecules that are made up of identical atoms, bonded together in the same way, i.e. they have the same connectivity.

Detailed explanation-2: -Enantiomers are stereoisomers that are non-superimposable mirror images. A molecule with 1 chiral carbon atom exists as 2 stereoisomers termed enantiomers (see the example below).

Detailed explanation-3: -Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable.

Detailed explanation-4: -STRUCTURAL IDENTIFICATION. Assertion: Stereoisomers which are not mirror image of each other are called diastereomers.

Detailed explanation-5: -What are Enantiomers? Enantiomers are stereoisomers, so, they are molecules with the same connectivity, but different spatial orientation. They differ in their arrangement at positions called chiral centers, made of one central atom connected to four unique atoms, or groups of atoms.
