why'd u have to ask that? A covalent compound is a compound in which the atoms that are bonded share electrons rather than transfer electrons from one to the other. While ionic compounds are usually formed when metals bond to nonmetals, covalent compounds are formed when two nonmetals bond to each other.
The big question that students frequently have is, "Why do elements share electrons? After all, wouldn't electrons rather grab electrons outright? That's what happens when ionic compounds are formed."
The reason that nonmetals have to share electrons with each other has to do with electronegativity. Recall that electronegativity is a measure of how much an element pulls electrons away from other elements it is bonded to. Metals generally have very low electronegativities (they don't much want to grab electrons) while nonmetals have high electronegativities (they really want to grab electrons). The reason for this trend is the octet rule, which says that all elements want to have the same number of electrons as the nearest noble gas, because noble gases are unusually stable. When metals bond to nonmetals, ionic compounds are formed because the metal atoms don't want electrons and easily give them to nonmetals that do want electrons.
It's a different story when two nonmetals bond with each other. Instead of having one element give electrons to another, we run into a case where we have two elements that have roughly the sameelectronegativity. As a result, neither element can steal electrons from the other. As a result, if either of them are going to be like the nearest noble gas, they'll have to share electrons rather than transfer them.
"Like dissolves like" is a principle in chemistry that refers to the tendency of substances with similar polarities to mix or dissolve in each other. For example, polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes. This principle helps predict solubility and interactions between different substances.
Ionic compounds are the most common compounds that dissolve in water because they have positive and negative dipoles. The positive and negative dipoles of water attract the negative and positive dipoles of the ionic compound, pulling it apart between the dipoles. However, certain non-ionic substances also dissolve easily in water. For example, sugar and alcoholic beverages made with alcohols such as ethanol are also soluble in water. Ethanol is especially soluble in water because the molecule contains a polar O—H bond like those in water. Because it is similar to the form of an H20 molecule, it bonds to the H20 as if it were one. Similarly, the sugar molecule has many polar O—H molecules that can also bond with water molecules.
Two examples are plastic and wax. Both plastic and wax are non-polar substances and therefore do not dissolve in water, which is a polar solvent.
When sugar molecules dissolve in water, they are surrounded by water molecules that bond with them. This process breaks the sugar molecules apart, dispersing them evenly throughout the water. As a result, a sugar solution is formed where individual sugar molecules are no longer distinguishable.
Two types of solvents are polar solvents, such as water, which have a positive and negative charge, and nonpolar solvents, such as hexane, which do not have a charge and do not interact with polar molecules. These solvents are used to dissolve other substances in a solution.
yea water can dissolve polar compounds
Nonpolar compounds, such as oil or fats, will not dissolve in water because water is polar and nonpolar compounds do not interact well with polar substances.
Non-polar compounds are least likely to dissolve in water because water is a polar solvent and non-polar compounds do not interact well with polar substances. Ionic compounds and charged compounds are more likely to dissolve in water due to their ability to interact with the polar water molecules.
Ionic compounds would be least likely to dissolve in water as they are held together by strong electrostatic forces that are not easily broken by water molecules. Non-polar compounds are also unlikely to dissolve in water because water is a polar solvent and non-polar compounds are not attracted to water molecules.
it can, polar water molecules easily dissolve polar molecules, or ionic compounds such as salt.
Water is a polar molecule due to its uneven distribution of electrons, which allows it to interact with and dissolve other polar or ionic compounds. The positive and negative charges in water molecules interact with the charges on the ionic compounds, causing them to dissociate and dissolve in water. This ability to form hydrogen bonds with the ions in the compound helps water dissolve most polar ionic compounds.
Water dissolve sodium chloride because both are polar compounds.
Because compounds have a polar molecule - as water.
Polar compounds, such as salts and sugars, dissolve in water because water is a polar molecule. Nonpolar compounds, such as oils and fats, do not dissolve in water because they are not attracted to the polar water molecules.
No, carbon tetrachloride (CCl4) is not a polar solvent and therefore cannot dissolve ionic compounds which ionize in solution. Ionic compounds typically dissolve in polar solvents like water.
Because sodium chloride and water are both polar compounds.
Hexane is a non-polar solvent, so it will not dissolve in water. Kerosene is non-polar so it will dissolve in Hexane.
