Question

Look at the table below. Do you think that substance mathrm(C) is a simple molecular substance? no yes Substance & }(c) Melting point (( )^circ mathrm(C)) & Boiling point (( )^circ mathrm(C)) & Does it conduct electricity? A & 1538 & 2862 & Yes B & -101 & -35 & No C & -114 & -85 & No D & 801 & 1413 & Only when mollen/in solution E & -77 & -33 & No

Answer 1

YesSubstance C is a simple molecular substance.

Answer 2

## Step 1: Understand the properties of simple molecular substances. Simple molecular substances are usually gases, liquids or low melting point solids, because the intermolecular forces of attraction are weak. They do not conduct electricity because they do not have free electrons or ions.## Step 2: Analyze the properties of substance C in the table. Substance C has a low melting point of -114 degrees Celsius and a low boiling point of -85 degrees Celsius. It also does not conduct electricity.## Step 3: Compare the properties of substance C with the properties of simple molecular substances. The properties of substance C match those of simple molecular substances, which suggests that substance C is a simple molecular substance.
