ANSWER:
Step 1 of 5
(a) (S)-2-chlorobutane
Three-dimension representation:
Only one chiral centre present in the structure of (S)-2-chlorobutane which can be represented as follows:
Enantiomer:
Fischer projection plays a vital role in finding the enantiomer of a compound
The above structures A and B are non-superimposable, so A And B are enantiomers.
Diastereomer:
Diastereomers are the compounds which are not mirror images of each other and are non-superimposable.
