1

What is a lewis acid?

An electron pair acceptor, must have space in its outer shell to accept a pair of electrons.

2

What is a lewis base?

An electron pair donor must have a lone pair of electrons.

3

What happens during a Lewis acid base reaction?

A coordinate covalent bond is always formed when the base donates a pair fo electrons to the acid.

4

What are examples of a lewis acid base reactions?

Formation of a copper ion by a translation metal ion, the transition metal ion is the lewis acid and the ligand is the lewis base.

5

Why is the formation of a complex ion only an acid base reaction according to the lewis theory?

Not according to the bronzed lowry theory since there is no transfer of a proton.

6

What are other examples of a lewis acid and base?

A nucleophile is a lewis base and an electrophile is a lewis acid.
