Molecular compounds have relatively high boiling points?
Molecular compounds typically have lower boiling points compared to ionic compounds because of weaker intermolecular forces between molecules. The boiling points of molecular compounds increase with increasing molecular size and polarity. However, they generally have lower boiling points compared to ionic compounds due to the nature of the forces holding the molecules together.
What is binary compounds containing two non metals?
Binary compounds containing two nonmetals are typically covalent compounds where the atoms share electrons to achieve a stable electron configuration. These compounds tend to have lower melting and boiling points compared to ionic compounds. Examples include water (H2O), carbon dioxide (CO2), and ammonia (NH3).
What is the strongest force that exist between molecules of ammonia?
The strongest forces that exist between molecules of ammonia (NH₃) are hydrogen bonds. These occur due to the highly electronegative nitrogen atom, which attracts the hydrogen atoms from neighboring ammonia molecules, resulting in a strong interaction. This hydrogen bonding significantly influences ammonia's physical properties, such as its relatively high boiling point compared to other similar-sized molecules.
What type of solid does NH3 form?
NH3, or ammonia, typically forms a molecular solid when it crystallizes. In its solid state, ammonia molecules are held together by hydrogen bonds, resulting in a structure that is generally less dense than many ionic or covalent solids. These molecular solids have relatively low melting and boiling points compared to other types of solids. At low temperatures, ammonia forms a crystalline structure known as ammonia ice.
Why does water exist in liquid state?
At room temperature, water is in a liquid state because it has a high boiling point, as compared to gases that have relatively low boiling points.
Why does ammonia have a high boiling point?
Ammonia has a high boiling point because it forms hydrogen bonds between its molecules. These hydrogen bonds are relatively strong forces of attraction that require more energy to break, leading to a higher boiling point compared to other compounds of similar size.
What type of bonding does ammonia?
polar covalent
Molecular compounds have relatively high boiling points?

The boiling points of molecular compounds increase with increasing molecular size and polarity. However, they generally have lower boiling points compared to ionic compounds due to the nature of the forces holding the molecules together.
What are the intermolecular forces in ammonia?
The intermolecular forces in ammonia include hydrogen bonding, which occurs between the hydrogen in ammonia and the lone pair of electrons on the nitrogen atom of another ammonia molecule. These hydrogen bonds are relatively strong compared to other intermolecular forces and contribute to the higher boiling point of ammonia.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
What is binary compounds containing two non metals?
Binary compounds containing two nonmetals are typically covalent compounds where the atoms share electrons to achieve a stable electron configuration. These compounds tend to have lower melting and boiling points compared to ionic compounds. Examples include water (H2O), carbon dioxide (CO2), and ammonia (NH3).
Which have the highest boiling point mgo and cao or nacl and hcl or co2 and so2?
MgO and CaO have higher boiling points compared to NaCl and HCl, and CO2 and SO2. This is because MgO and CaO are ionic compounds that have stronger electrostatic forces between ions, leading to higher boiling points. NaCl and HCl are also ionic compounds but have lower boiling points compared to MgO and CaO. CO2 and SO2 are molecular compounds with weaker intermolecular forces, resulting in lower boiling points compared to the ionic compounds.
What is the reason for ch3br or ch3f having a higher boiling point compared to other compounds?
The reason ch3br or ch3f have higher boiling points compared to other compounds is because they have stronger intermolecular forces due to the presence of hydrogen bonding.
Do ionic compounds have lower boiling points than polar covalent?
In general, ionic compounds tend to have higher boiling points compared to polar covalent compounds. This is because ionic compounds have strong electrostatic forces of attraction between positively and negatively charged ions, requiring more energy to break those bonds compared to the intermolecular forces found in polar covalent compounds.
Does ammonia evaporates when water is boiled?
Yes, ammonia is a volatile compound and will evaporate when water is boiled. This is because ammonia has a lower boiling point compared to water, so it will evaporate along with the water vapor.
What are the characteristic of a covalent?
Covalent bonds involve the sharing of electrons between atoms. They are typically formed between nonmetals and are relatively strong compared to other types of bonds. Covalent compounds tend to have lower melting and boiling points compared to ionic compounds.
How are the melting points and boiling point of molecular compounds different from ionic compounds?
Molecular compounds typically have lower melting points and boiling points compared to ionic compounds. This is because molecular compounds are held together by weaker intermolecular forces (such as Van der Waals forces) compared to the strong electrostatic interactions in ionic compounds.
