Question
Covalent compounds display which of these properties?Group of answer choicesThey display luster.They are hard, brittle solidsThey have high melting and boiling pointsTheir intermolecular forces are relatively weak.
Solution
Covalent compounds are known for having relatively weak intermolecular forces. This is because they consist of individual molecules that do not have strong attractions to each other.
They do not typically display luster. Luster is a property more commonly associated with metals and ionic compounds.
Covalent compounds are not usually hard, brittle solids. This is a characteristic more typical of ionic compounds, which have a crystalline lattice structure.
Lastly, covalent compounds do not generally have high melting and boiling points. This is because the weak intermolecular forces require less energy to break, so these compounds can change state at lower temperatures.
So, the correct answer is: Their intermolecular forces are relatively weak.
