3. State the reason for the following: (10)(i) HI has more covalent character than HCl.(ii) Ionic compounds are more soluble in water than benzene.(iii)
The radius of S2-ion is larger than the radius of Cl-ion.(iv) In NaBr crystal, each ion is octahedrally surrounded by ions of opposite charge.(v) In HF, the experimental bond length value is less than the sum of covalent radii.
