Interpretation:
The reason why the given enantiomers of a compound can be separated even though the one of the group attached to nitrogen is a lone pair has to be explained.
Concept introduction:
Stereoisomers are isomers which have different spatial arrangement in spite of same bond connectivity. Stereoisomers are due to the presence of stereocenter. Stereocenter may be an atom axis (bond) or plane from which interchanging of two groups leads to stereoisomers.
Enantiomers are stereoisomers, in which they are mirror images of each other.
Asymmetric center is a stereocenter which arises to a compound if any atom is bonded to four different groups.
If one of the four groups attached to nitrogen is lone pair, then inversion of amine takes place for acyclic
The bond angle of cyclopropane is
