Question

acetone and sodium chloride both have a similar mass. explain why their other properties differ.
which statements are true regarding these two compounds? check all that apply.
property\tacetone\tsodium chloride
formula\t$c_3h_6o$\t$nacl$
melting point\t$-94^{circ}c$\t$801^{circ}c$
state at room temperature\tliquid\tsolid
electrical conductivity\tlow\thigh
acetone is a covalent compound, while sodium chloride is an ionic compound.
ionic compounds conduct electricity well in their solid (pure) form.
covalent compounds have weak attractions between molecules, resulting in low melting points.

Explanation:

Acetone is a covalent compound formed by sharing of electrons between non - metals, resulting in weak intermolecular forces and low melting point and poor electrical conductivity. Sodium chloride is an ionic compound formed by transfer of electrons between a metal and a non - metal, having strong electrostatic forces between ions, high melting point and good electrical conductivity in molten or aqueous state (not in solid pure form as ions are fixed in lattice).

Answer:

Acetone is a covalent compound, while sodium chloride is an ionic compound.
Covalent compounds have weak attractions between molecules, resulting in low melting points.
