Covalent bonds themselves are not liquids or any other phase. The phase distinction between solids, liquids, and gases is a property of substances, not bonds. Compounds with covalent bonds are more likely to be liquid than ionic compounds because the inter-molecular forces are usually weaker in compounds with covalent bonds.
What else can I help you with?
Why are covalent compounds usually turn into gases or liquids at room temperature?
Covalent compounds have weaker intermolecular forces compared to ionic compounds, making it easier for them to break apart and move freely as gases or liquids at room temperature. The lack of strong electrostatic forces between molecules allows them to have lower melting and boiling points.
What are some characteristic of most covalent compounds?
Most covalent compounds have low melting and boiling points, are usually gases or liquids at room temperature, and tend to be poor conductors of electricity. They also have localized bonds between nonmetal atoms, where electrons are shared.
Are ionic compounds usually gases or liquids?
Ionic compounds are usually solids at room temperature, rather than gases or liquids. This is because they have strong electrostatic forces holding their ions together in a stable lattice structure.
Are ionic compounds usually liquids or gasses?
Ionic compounds are typically solid at room temperature. They have high melting and boiling points due to the strong electrostatic forces between the ions in the crystal lattice. However, there are some exceptions where ionic compounds can be liquids, like molten salts or certain ionic liquids.
Are covalent compounds crystalline solids?
Not usually no. However, covalently bonded polymers will often have crystalline domains - these are called spherulites. So the polymer is rarely perfectly amorphous. PET is one such polymer. see related link for more information.

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 do you differentiate simple molecular compounds and giant molecular compounds?
Simple molecular compounds have discrete molecules held together by weak intermolecular forces, while giant molecular compounds have repeating units bonded together by strong covalent bonds. Simple molecular compounds typically have low melting and boiling points and are often gases or liquids at room temperature, while giant molecular compounds tend to have high melting and boiling points and are usually solids at room temperature.
What are the characteritics of covalent compounds?
Covalent compounds are formed by the sharing of electrons between atoms. They typically have lower melting and boiling points compared to ionic compounds. Covalent compounds are often insoluble in water and non-conductive in their solid state.
Covalent compounds are usually composed of two?
Covalent compounds are usually composed of two non-metal atoms. These atoms share electrons to form covalent bonds, resulting in a stable molecule. Examples include water (H2O) and methane (CH4).
What is the relationship between a compound's chemical bond type and its phase at room temperature?
Usually different compounds have a specific freezing, melting, and boiling point. There are all types of different compounds out in the world but it also depends on their intermolecular forces. In weak bonds, volatility and pressure is high, while boiling point is low. In strong bonds, volatility and pressure is low, while boiling point is high.
What group of substances do not usually form organized crystal lattices in solid state Ionic compounds metals polar covalent compounds or non-polar covalent compounds?
All of them can form organized crystal lattices.
What is the properties of covalent bond?
Covalent compounds generally have much lower melting and boiling points that ionic compounds. Covalent compounds are soft and squishy. Covalent compounds tend to be more flammable that ionic compounds. Covalent compounds don't conduct electricity in water. Covalent compounds aren't usually very soluble in water.
