Question

Which of the following compounds would have the lowest melting point?
(Points : 1)
sodium chloride

sucrose

potassium chloride

aluminum oxide

Answer 1

Sucrose. Sucrose is made of all nonmetals, the others appear to be ionic bonds, while sucrose bonds covalently, since its a carbon compound.
Nonmetals tend to have lower melting points than metals, so potassium, aluminum, and sodium compounds, automatically have a higher melting point than any nonmetal compound.
