To determine: If the compound is chiral; it’s most symmetric conformation and asymmetric carbon atoms (to be marked by a star) and mirror planes if possible.
Interpretation: The validation of the fact that the given compound is chiral is to be stated; most symmetric conformation of the compound and any mirror plane if possible are to be drawn and asymmetric carbon atoms are to be marked by star.
Concept introduction: An asymmetric carbon atom is represented as a cross in Fisher projection. The carbon chain is kept along the vertical line. The groups attached to asymmetric carbon atoms are arranged according to their configuration in Fisher projection. The enantiomers of a chiral compound can be named with the help of right hand and left hand configuration. In fisher projection, chiral carbon atom is represented by a cross. When two groups on a fisher projection are interchanged, the configuration of chiral carbon also changes from (R) to (S) aur (S) to (R).
