Question

2. The compound shown below contains a chirality center at nitrogen. Why can't individual stereoisomers of this compound be isolated at room temperature? (3 points) -CH, н,с 'N H

Answer 1

The solution is
We are are given given the amine molecule HC CH₂ idal structure where all It exists ca by humide the groups are different ie, hydrogen, ethyl methyl group and the fourth position is occupied by lone pour on Nitrogen. H₂ C. CH3 H Because of the 3 different substituents and exists which leads q zo Lone stereoisomers paire Chinality Υγγύη Plane CZ CH3 "G CH3 HC,.. But N shows fluxonial behavior. This means that the stereoisomers are rapidly interconverted by inversion as (CHA Q CH₂ 1₂C. 1//CH3 Н CH3 H Н Planar transistion state

very small energy As zhis inversion is is eas This inversion has a bawie. energy for sily percovided at room temperature due zo thermae energy, this inter conversions of a stereo - isomers keeps occurring rapidly Hence, the 2 steamed isomers are in indistinguished uished and Cani be isolated on woom temperature.
