Which statement is true regarding the following structure?
Which statement is true regarding the following structure?
It is a chiral molecule
It exists in two resolvable optically active forms
Both (a) and (b)
Neither (a) nor (b)
Solution
In amines, $\mathrm{N}$ is $s p^{3}$ hybridised and thus has pyramidal shape. In the given structure, since the three alkyl groups are different, and the fourth corner of the pyramid is occupied by lone pair of electrons, the molecule is chiral. However, the two enantiomers of the amine are not resolvable because of their rapid interconversion through a transition state having planar structure $\left(s p^{2}ight.$ hybridised nitrogen)
