Answer: CaCl2 and KI- ionic

PCl3 and CH4-dispersion forces

NH2OH- hydrogen bonding

Part B

Smaller ions.

Explanation:

The smaller the ions the easier it is for them to be packed into a well ordered crystal lattice. The strength of ionic interaction always depend on the relative ion sizes. The smaller the ions the stronger the bond. Large ions do not easily pack into crystal lattices.

1) The type of interparticle force that has the greatest influence on the physical properties for each substance is;

CaCl2 and KI; ionic bonding

CaCl2 and KI; ionic bondingPCl3 and CH4; dispersion forces

CaCl2 and KI; ionic bondingPCl3 and CH4; dispersion forcesNH2OH; hydrogen bonding

2) The factor that will result in a stronger ionic bond overall is; Smaller ions

1) We want to Identify the type of interparticle force that has the greatest influence on the physical properties for each substance. Let us look at the options;

  • For CaCl2 and KI, the elements Calcium and Potassium that form the chloride are metals and as such they form ionic bonds with the halogens Chlorine and Iodine. Thus, ionic bonding has the greatest force here.

  • For PCl3 and CH4, they possess forces that are dispersive and as such their structural arrangement distribute electrons to any surrounding atoms and molecules. Thus, the forces of dispersion have the greatest force here.

  • For NH2OH, as a result of the presence of Hydrogen (H) and Oxygen(O) atoms, the bond present in it will be a hydrogen bond. Thus hydrogen bond has the greatest force here.

2) Bond strength, depends largely on the charges present on each ion as well as the distance between each ion. Thus, it means ions that are Small and highly charged will form stronger bonds while ions that are large, minimally charged will form bonds that are weak.

Thus, smaller ions results in stronger ionic bond overall.
