What causes the differences in melting points and boiling points between ionic and covalent compounds molecular substances?
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic compounds.

Are covalent molecular compounds soluble?
Solubility of a substance in water depends on the type of interaction predominates in the compound and the solvent.The solubility of any compound follows the principle "like dissolves like".So if a covalent molecular compound is polar then it dissolves in a polar solvent and if it is non polar or hydrophobic then it dissolves in a nonpolar solvent
Do substances that usually contain covalent bonds have a giant or simple molecular structure?
Substances that usually contain covalent bonds have a simple molecular structure. Examples include elements like oxygen and compounds like methane. Giant molecular structures are typically found in substances with strong covalent bonds, such as diamond and quartz.
Are covalent molecular compounds ductile?
No, covalent molecular compounds are typically not ductile because they are made up of individual molecules held together by covalent bonds. These compounds have a molecular structure that does not allow for the same type of malleability or flexibility as metallic or ionic compounds.
Can molecular compounds have covalent bonds?
Yes, molecular compounds typically have covalent bonds. Covalent bonds involve the sharing of electron pairs between atoms, which is common in molecular compounds where atoms are joined together to form molecules. Examples include diatomic molecules like hydrogen gas (H2) and oxygen gas (O2), as well as larger molecules like methane (CH4) and water (H2O).
Is a covalent compound a molecular compound?
Yes, a covalent compound is a type of molecular compound. Covalent compounds are formed by sharing electrons between atoms, leading to the formation of molecules. These compounds typically consist of nonmetals bonded together.
Are molecular substances the same as covalent compounds?
Usually, however, the are a few covalent compounds, such as silicon dioxide (SiO2) that form covalent networks rather than molecules.

How are the properties of molecular compounds different from those of ionic cmpounds?
Molecular (covalent) compounds are not dissociated in water.

Why don't covalent molecular compounds conduct electricity?
Covalent substances do not conduct electricity because they are sharing electrons, hence they are in a fixed position and are not able to move around and contribute to movement of the electric current.
What are the smallest units of covalent molecular compounds called?
The smallest units of covalent molecular compounds are called molecules. They are formed when atoms share electrons to achieve a stable electron configuration.
What are formulas for a covalent compounds called?
Formulas for covalent compounds are called molecular formulas. They show the types and numbers of atoms in a molecule.
What are the 7 types of compounds?
Ionic compounds Covalent compounds Metallic compounds Molecular compounds Acidic compounds Basic compounds Organic compounds
