Question

Correct configuration of the following is:

A.1S,2S
B.1S,2R
C.1R,2S
D.1R,2R

Answer 1

A molecule or ion is chiral if it cannot be superimposed on its mirror image by any combination of rotations and translations. This property is further known as chirality. Moreover, these different arrangements of atoms are studied in the branch of chemistry known as stereochemistry.

Complete step by step answer:
Stereochemistry is basically a systematic presentation of a specific field of science that deals with the spatial arrangements of atoms and groups in a molecule. Further, it deals with the study of molecules that exhibit chirality, which is a geometric property of molecules that make them superimposable on their mirror images.
Further, another branch of 3D chemistry known as dynamic stereochemistry involves the study of effects of different spatial arrangements of atoms in a molecule on the rate of a chemical reaction.
Now, the configuration of the given compound is 1S,2S. Basically in filing of the electrons we have different rules such as Hund’s rule, Aufbau principle, Pauli Exclusion Principle and many more. Basically, the electronic configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.

Hence, option A is correct.

Note: Stereoisomers can be broadly classified into two types, namely enantiomers and diastereomers. Basically, when two isomers are mirror images of each other, then the type of isomers are known as enantiomers and isomerism is known as enantiomers. They are stable compounds that differ in their spatial arrangements whereas diastereomers are the isomers that do not behave as mirror images of each other. These isomers vary in physical properties and chemical reactivity.
