Identify the Lewis acids and Lewis bases in the following reactions: 1. H+ + OH- <-> H2O Lewis acid: Lewis base:
2. Cl- + BCl3 <-> BCl4- Lewis acid: Lewis base:
3. K+ + 6H2O <-> K(H2O)6+ Lewis acid: Lewis base:

1.  Lewis acid : , Lewis base :

2. Lewis acid : , Lewis base :

3. Lewis acid : , Lewis base :

Explanation:

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

1.

As gained electrons to complete its octet. Thus it acts as lewis acid. acts as lewis base as it donates lone pair of electrons to electron deficient specie .

2.

As is short of two electrons to complete its octet. Thus it acts as lewis acid. acts as lewis base as it donates lone pair of electrons to electron deficient specie .

3.

As is short of electrons to complete its octet. Thus it acts as lewis acid. acts as lewis base as it donates lone pair of electrons to electron deficient specie .
