Concept Introduction:
▸ Lewis acids are electron pair acceptors.
▸ Lewis bases are electron pair donors.
▸ The valence shell electron pair repulsion (VSEPR) theory predicts the arrangement of atoms in molecules and ions.
▸
▸ They can act as nucleophiles and electrophiles in organic reactions.
▸ Amines can be classified into three categories: primary amines, secondary amines, and tertiary amines.
▸ If the nitrogen atom is directly attached to only one other carbon atom, the amine is a primary amine.
▸ If the nitrogen atom is directly attached to two other carbon atoms, the amine is a secondary amine.
▸ If the nitrogen atom is directly attached to three other carbon atoms, the amine is a tertiary amine.
▸ Higher the electron density around the nitrogen atom, more available is the electron pair to donate. Electron donors are Lewis bases.
▸ The reaction is Lewis acid- base reaction. The trimethyl amine donates a pair of electrons, so it acts as a Lewis base and
▸ Hybridization is the concept of mixing atomic orbitals into new hybrid orbitals which are suitable for pairing of electrons to form
▸ Hybrid orbitals are very useful in the explanation of molecular geometry.
▸ A trigonal planar geometry has
▸ A tetrahedral geometry has
▸ When one s-orbital and one p-orbital combine, it forms two
▸ When one s-orbital and two p-orbital combine, it forms three
▸ When one s-orbital and three p-orbital combine, it forms four
