Expert Answer

Step 1

The compound KCl is composed of K+ cation and Cl- anion. Thus, the interaction between the cation and anion leads to the formation of ionic compound between them. Therefore, KCl is an ionic compound

The compound BCl3 has an unequal sharing of electrons and the elecronegativities of Be is 2.0 and Cl is 3.0. Thus, due to difference in electronegativities and unequal sharing of electrons leads to the formation of polar covalent bonds between boron and chlorine.

Step 2

The compound P4 has an equal sharing of electrons and the elecronegativities of phosphorus atoms are equal. Thus, the bond present in P4 is non polar covalent bond.

The compound Br2 has an...
