ANSWER:
Solution 106P
Here, we are going to explain the Lewis structure for each compound containing ionic and covalent bond.
(a) RbIO2
RbIO2 contains both the ionic (Rb-O) and covalent (O-I) bond. Rb-O is ionic due to the difference in large electronegativity between Rb and O whereas IO2-is polyatomic anion having I-O covalent bond by sharing of electrons between them.
The Lewis structure for RbIO2 is given below,
Valence electron of I = 7
Valence electron for O = 6
Valence electron for Rb =1
Total valence electrons = 1+ 7+ 6x2 = 20 e
RbIO2------> Rb+ +IO2-
The Resonance structure of IO2- ion is as follows
