Question

Let the starred carbon in the given amine has "R" configuration. What is the isomeric relationship between the two form of this compound that are inter converted by amine inversion. Give your answer in integer form
[Give : 1 for identical, 2 for enantiomer, 3 for diastereomer, 4 for functional isomer.]

Answer 1

The product will be diastereomers as amine inversion will change the configuration of N only and not that of chiral carbon, so the answer is 3.
