Look at sample problem 18.15 in the 8th ed Silberberg book. Identify the Lewis acids and Lewis bases in the following reactions:
H+ + OH- <-> H2O Lewis acid: Lewis base: Cl- + BCl3 <-> BCl4- Lewis acid: Lewis base: K+ + 6H2O <-> K(H2O)6+ Lewis acid: Lewis base:
1 answer:
Answer:
1. H+ + OH- <--------> H2O
H+ is a Lewis acid
OH- is a Lewis base
2. Cl- + BCl3 <---------> BCl4-
Cl- is a Lewis base
BCl3 is a Lewis acid
3. K+ + 6H2O <------> K(H2O)6+
K+ is a Lewis acid
H2O is a Lewis base
Explanation:
By definition, Lewis acid is an electron pair acceptor while a Lewis base is an electron pair donor.
Potassium ion accept electron pairs from 6 water molecules which donate the electron pairs.
