Substances of the formula CL2. HCl. KCl are formed by chemical bonds, respectively: a) covalent non-polar, covalent polar, ionic b) ionic, covalent non-polar, covalent polar c) ionic, covalent polar, covalent non-polar d) covalent polar, ionic, covalent non-polar.
Answer: a
Cl2 is a covalent non-polar bond because two are the same elements. on the outer level there are 7 electrons, one of them is unpaired, these unpaired electrons form a bond.
HCl is covalent polar because the pair of electrons is shifted towards the more electronegative element chlorine.
KCl is an ionic bond, because potassium is a cation with +, and chlorine anion with -, and opposite charges attract.
