Question

Consider the reaction and indicate which reactant is the Lewis acid and which is the Lewis base. C H 3 C O Cl and F e C L 3 give F e C L 4 minus and C H 3 C O plus. The structure of C H 3 C O C L is a central carbon double bonded to an oxygen containing two lone pairs. The central carbon is also bonded to a methyl group and a chlorine, which contains three lone pairs. The product is a central carbon with a plus charge, which is double bonded to an oxygen which contains two lone pairs. THe carbocation is also bonded to a methyl group. Identify the true statement(s).

Answer 1

`\mathbf{FeCl_3}` is the lewis acid

`\mathbf{CH_3COCl}` is the lewis base

Step-by-step explanation:

The Lewis acid is a compound capable of accepting a doublet of electrons and which has an electronic gap on its valence layer.

The lewis base is a compound capable of donating a doublet of electrons.

A Lewis acid associates with a Lewis base through a covalent bond (sharing of two electrons between two atoms). The reaction between an acid and a Lewis base produces a compound called the Lewis adduct.
