Structure of Amines Preparation and Properties
→ In amines, nitrogen atom undergoes sp3 hybridisation forming four sp3 hybrid orbitais. Three of these orbitais have unpaired electrons and overlap with carbon atom of alkyl group or orbital of hydrogen atom.
→ The fourth hybrid orbital contains a lone pair of electron because of the presence of these bonds, the geometry of the molecule is pyramidal and the bond angle is less than 109.5°.
