They form chemical compounds which may or may not be soluble in certain other chemical compounds.

Covalent and Ionic: When two atoms share electrons, they form a covalent bond. Answer : isopropyl alcohol ( C3H8O ) is a Covalent bond What is chemical bond, ionic bond, covalent bond? We were told its not so clearly cut. A bond can be covalent, ionic or metallic. Chemical bond A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. As there are no ions present in the formula of Ethanol an ionic bond can not be made. NaHCO3 (sodium bicarbonate) is neither polar nor non-polar in its pure form because it is not a covalent compound. The general rule is polar solvents dissolve polar compounds; and non-polar solvents dissolve non-polar compounds. Question : Is isopropyl alcohol ( C3H8O ) an ionic or covalent bond ? Question: Is ethanol an ionic or covalent bond ? The ions are atoms that have gained one or more electrons (known as anions, which are negatively charged) and atoms that have lost one or more electrons (known as cations, which are positively charged). H2O is a polar covalent compound due to difference in electronegativities of hydrogen (less electronegative) and oxygen (more electronegative). And this I think is the main reason: hydrogen has fairly high Pauling electronegativity (2.20), rather close to oxygen (3.44), which seems polar covalent overall (and why we get hydrogen bonding with water). There are two main types of bonds: covalent and ionic bonds. NaHCO3 is considered polar in one of them, but not in the other. A covalent bond can be polar or nonpolar, but not ionic.

Just to be clear I would reword the question as bonds are not soluble. ethanol and hexane are organic compounds which are non-polar solvents thus they do not dissolve in water. Chemical bond A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. There are "in between" states like polar covalent, where one side of the bond is stronger but not fully ionic. But even at ∆EN of 2 it might still be 10% covalent. They are covalent compounds. Polar usually refers to when covalent compounds have polar bonds (caused by the unequal sharing of electrons). ethanol is Covalent bond I'll tell you the ionic or Covalent bond list below. When the difference in electronegativity (ill shorten it to ∆EN) is higher than 1.7 we say its mostly ionic, when ∆EN is between 0.5 and 1.7 its mostly covalent, and below 0.5 its mostly metallic bond. In covalent bonding electrons are shared, electrons are transferred in ionic bonding and electrons move about in a sea of electrons in metallic bonds.
