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

- Salicylic acid, HOC6H4CO2H, and its derivatives have been used as pain relievers for a long time. Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the barkof the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in 1838.(a) Both functional groups of salicylic acid ionize in water, with Ka = 1.0 × 10−3 for the—CO2H group and 4.2 × 10−13 for the −OH group.
