PROBLEM 105P

Each compound listed contains both ionic and covalent bonds. Write the ionic Lewis structure for each one including the covalent structure for the polyatomic ion. Write resonance structures if necessary.

(a) KOH

(b) KNO3

(c) LiIO

(d) BaCO3

Step-by-Step Solution:
Step 1 of 3

Solution 105P

Here, we are going to explain the Lewis structure for each compound containing ionic and covalent bond.

KOH

KOH contains both the ionic (K-O) and covalent (O-H) bond. K-O is ionic due to the difference in large electronegativity between K and O (3.5-0.9 = 2.6).An O-H bond can ionize in some cases. There is already a negative charge on oxygen in OH. So it is more difficult to put a second negative charge on the oxygen by ionizing the O-H bond as well.

The Lewis structure for KOH is given below,

Valence electron of K = 1

Valence electron for O = 6

Valence electron for H =1

KOH------> K+ + OH-

(b) KNO3

KNO3 contains both the ionic (K-O) and covalent (O-N) bond. K-O is ionic due to the difference in large electronegativity between K and O (3.5-0.9 = 2.6) whereas NO3 is polyatomic anion having N-O covalent bond by sharing of electrons between them.

The Lewis structure for  KNO3  is given below,

The Lewis structure for KNO3 is given below,

Valence electron of K = 1

Valence electron for O = 6

Valence electron for N =5

Total valence electrons in NO3- is = 5+ 3x 6 +1 = 24 e

KNO3------> K+ + NO3-

The Resonance structure of NO3- ion is as follows

The Lewis structure for KNO3 is given below,

(c) LiIO

LiIO...
