Discuss the optical activity of tertiary amines of the type R_(1)R_(2)R_(3)N: |
Answer» SOLUTION :TERTIARY amines have pyramidal geometry with `sp^(2)`. Hybridization at nitrogen. It should be a chiral molecule (assuming LONE pair to be a substituent) Thus, tertiary amines exist as racemic MIXTURE but they canot be resolved. This is due to the reason that the energy difference between the isomers is very small (25 kJ `"mol"^(-1)`) Hence, rapid nitrogen or amine inversion takes place.
