The correct option is c i.e, have a low melting point. Covalent compounds have a low melting point due to weaker intermolecular forces. They are formed from two or more nonmetal elements and share electrons in a chemical bond.
Understanding the properties of covalent compounds is essential in Chemistry. Let's analyze each option provided:
Option A: Covalent compounds are not formed from one metal and one nonmetal. Instead, they are formed from two or more nonmetal elements.Option B: This option is incorrect because, in covalent bonds, atoms share electrons rather than exchange them.Option C: Covalent compounds indeed have a low melting point compared to ionic compounds. This is due to the weaker intermolecular forces present in covalent compounds.Option D: Correct. Covalent bonds generally have weaker bonds than ionic compounds, making it easier to melt or boil covalent compounds.Given the above explanations, the correct answer is Option C: Covalent compounds have a low melting point.
