Question

Identify all the different types of bonding (ionic, covalent, or both) in the following compounds: Br(ClO4)2, ClO2, NaCl

Ionic Only

Covalent Only

Both

Answer 1

Solution :-

When the metal and non metals are present in the formula then they forms ionic bonds

when non metal and non metal elements forms the bond then they shape pair of electrons to form the bond therefore the bond is covalent bond. When the electronegativity difference is less than 0.5 then it is non polar covalent bond and when electronegativity difference is 0.5 to 1.7 then bond is polar covalent bond.

following is the types of bond which are present in each molecule

Br(ClO4)2 = Ionic bond and covalent bond (both)

ClO2 = covalent bond only

NaCl = Ionic bond only
