2. For each compound, state whether its bonding is ionic, covalent, or a mixture of ionic and covalent, then draw a Lewis structure to show the bonding in the compound: Please explain why it is ionic, covalent or a mixture of ionic and covalent.

a) CH2Cl2 b) NaOCH3 c) HCO2Na

Solutions

Expert Solution

We obtain the ionic or covalent character by determining the electronegativity difference between the participation atoms. In general, a non-metal bond with non-metal is covalent while a non- metal bond with metal is ionic bond.

a) CH2Cl2

We see that all elements are non-metals and therefore form covalent bonds.

b) NaOCH3

We see that a metal Na is present. This metal will form an ionic bond with the oxygen while the remaining bonds will be covalent. It has a mixture of ionic and covalent bonds.

c)HCOONa

Just like in b), a mixture of ionic and covalent bonds.

Question 21 What is the fundamental difference between covalent and ionic bonding? In a covalent bond, the partners share a pair of electrons; in an ionic bond, one partner accepts electrons from the other. Covalent bonds form between atoms of the same element; ionic bonds form between atoms of different elements. Covalent bonding involves only the outermost electron shell; ionic bonding also involves the next electron shell inside the outermost shell. In covalent bonding, both partners end up with filled...
