Question
Explain the structure of amine compounds by drawing a diagram.

Answer
$\rightarrow$ Like ammonia, nitrogen atom of amines is trivalent and carries an unshared pair of electrons.
$\rightarrow$ Nitrogen orbitals in amines are therefore, $SP^3$ hybridized and the geometry of amines is pyramidal.
$\rightarrow$ Each of the three $SP^3$ hybridized orbitals of nitrogen overlap with orbitals of hydrogen or carbon depending upon the composition of the amines.
$\rightarrow$ The fourth orbital of nitrogen in all amines contains an unshared pair of electrons.
$\rightarrow$ The angle $\ce{C-N-E }($Where $E$ is Cor $H)$ is less than $109.5^{\circ}$
$\rightarrow$ For instance, it is $108^{\circ}$ in case of trimethylamine as in the figure below:
