Problem
The physical properties of five solids labelled A, B, C, D, and E are summarized below. The substances are an ionic compound, a non-polar molecular solid, a metal, a polar molecular solid, and a covalent-network substance. Classify each correctly. A: insoluble in water, conducts as a solid, third to melt. B: insoluble in water, does not conduct as a solid, highest melting point. C: soluble in water, solution does not conduct, second to melt. D: insoluble in water, does not conduct as a solid, lowest melting point. E: soluble in water, solution conducts, does not conduct as a solid, fourth to melt.
