Hybridization in aniline refers to the mixing of atomic orbitals to form hybrid orbitals in the molecule aniline. This process allows for the formation of stronger bonds and influences the molecule's shape and properties.
The nitrogen atom in aniline has a sp2 hybridization state. This means that one s orbital and two p orbitals combine to form three sp2 hybrid orbitals, which are used to form bonds with other atoms.
The sp2 hybridization of nitrogen in aniline allows for the formation of a delocalized pi bond, making it more reactive than a typical amine. This makes aniline a better nucleophile and electrophile in chemical reactions.
No, the lone pair of electrons on the nitrogen atom in aniline does not participate in hybridization. The sp2 hybrid orbitals are formed from the three outermost orbitals of the nitrogen atom, leaving the lone pair unhybridized.
The hybridization of the carbon atoms in aniline (sp2) allows for the formation of strong pi bonds, making the molecule more stable. This also contributes to the planar structure of aniline, which further increases its stability.
