water, because of its polarity. This is caused by the oxygen molecule having a higher electron affinity, which means that the electrons of the hydrogen molecules more or less hang out around the oxygen causing the oxygen to be partially negative and the hydrogen ends to be partially positive. This is what is called a dipole moment which is why ionic (positive or negatively charged) and molecular (polar covalent) compounds are able to dissociate in the solvent(water).
Water is known as the universal solvent because of its ability to dissolve many ionic and molecular compounds due to its polar nature. The polar water molecules can surround and break apart the ions and molecules, allowing them to become dispersed in the solution.
Water dissolves so many substances because water is polar. The atoms of water has partial charges which enable it dissolves many substances.

Is sif4 ionic or molecular?
SIF4 is a molecular compound because it consists of covalent bonds between silicon and fluorine atoms. Ionic compounds involve the transfer of electrons between a metal and a non-metal.
Is a brittle compound a molecular compound?
No, a brittle compound does not necessarily indicate it is a molecular compound. Brittle compounds can be either molecular or ionic, depending on their chemical bonding. Brittle molecular compounds typically have covalent bonds, while brittle ionic compounds have ionic bonds.
Why is na2so4 not a molecular formula?
Na2SO4 is not a molecular formula because it represents an ionic compound, sodium sulfate. In ionic compounds, the elements are held together by ionic bonds rather than sharing electrons in covalent bonds like in molecular compounds. The formula Na2SO4 indicates that there are two sodium ions (Na+) for every sulfate ion (SO4^2-).
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.
Why dont molecular compounds conduct electricity when dissolves in water?
Molecular compounds do not conduct electricity when dissolved in water because they do not dissociate into ions. Ionic compounds dissociate into ions in water, which allows them to carry an electric current. Since molecular compounds do not break apart into ions, they do not have the ability to conduct electricity in water.
Water dissolves many ionic and molecular compounds why?
because it is a polar molecule
How can water dissolve some ionic compounds as well as some molecular compounds?
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.
What are the difference in conductivity between ionic and molecular compounds?
Ionic compounds typically have higher conductivity than molecular compounds because ionic compounds dissociate into ions in solution, allowing for the flow of electric current. Molecular compounds, on the other hand, do not dissociate into ions in solution and therefore exhibit lower conductivity.
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.
How do ionic and molecular compounds differ in physical properties?
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
Why do you put prefixes in front of molecular compositions but not ionic compounds?
Just because
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
Does water dissolve most things?
Yes. Water is known as a very good solvent mostly because of its ionic structure. Mostly water dissolves ionic compounds because of the like dissolves like.
How compared with the melting points of ionic compounds the melting points of molecular solids tend to be?
The melting points of molecular solids are lower compared to ionic compounds. This is because molecular solids are held together by weaker intermolecular forces, such as van der Waals forces, which are easier to overcome than the strong electrostatic forces present in ionic compounds.
How does melting point compare among molecular compounds and ionic compounds?
Molecular compounds tend to have lower melting points compared to ionic compounds. This is because molecular compounds are held together by weaker intermolecular forces, such as van der Waals forces or hydrogen bonds, whereas ionic compounds are held together by strong electrostatic forces between ions. The higher the melting point, the stronger the bonds in the compound.
How can molecular compounds be distinguished from ionic compounds?
Molecular compounds are formed by sharing electrons between atoms to create covalent bonds, while ionic compounds are formed by transferring electrons from one atom to another to create ionic bonds. Molecular compounds typically have lower melting and boiling points compared to ionic compounds, which have high melting and boiling points due to strong electrostatic forces between ions. Molecular compounds are typically composed of nonmetals, while ionic compounds are composed of metals and nonmetals.
Sodium chloride dissolves in water because it is a blank compound?
ionic However, it should be noted that not all ionic compounds are water soluble.
