Why is water an excellent solvent for most ionic compounds and polar covalent molecules but not for non-polar compounds?
Water is an excellent solvent for ionic compounds and polar covalent molecules because of its polarity. The partially charged regions of water molecules attract and surround ions and polar molecules, allowing them to dissolve. Non-polar compounds lack the partial charges needed for water molecules to effectively interact and dissolve them.
What else can I help you with?
Are covalent compounds soluble in hexane?
Yes, covalent compounds are generally soluble in nonpolar solvents like hexane due to their similar polarity. Covalent compounds tend to dissolve well in nonpolar solvents because they share similar intermolecular forces, such as London dispersion forces.
What do nonpolar covalent molecules share?
Nonpolar covalent molecules share electrons equally between the atoms, leading to a symmetrical distribution of charge and no net dipole moment. This results in their nonpolar nature and lack of attraction to polar molecules.
Are hydrophobic interactions covalent or non covalent?
Hydrophobic interactions are non covalent interactions between nonpolar molecules or regions within a molecule. They are based on the tendency of nonpolar molecules to minimize contact with water molecules.
Why covalent compound is insoluble in water?
Covalent compounds are typically nonpolar molecules, meaning they do not readily interact with water molecules which are polar. Due to this difference in polarity, covalent compounds are generally insoluble in water. These compounds lack the ability to form hydrogen bonds with water molecules, making it difficult for them to dissolve in water.
Why do covalent compounds dissolve in ethanol not in water?
The polar covalent compounds are easily soluble in water as HCl, HNO3, H2SO4, Glucose and most of the sugars, Sugar has many polar covalent bonds, in the C-O-H groups, and the molecules of sugar fit easily into the hydrogen bonded microstructure of liquid water.

Are all compounds with polar covalent bonds are polar molecules?
No, not all compounds with polar covalent bonds are polar molecules. Whether a molecule is polar or nonpolar depends on its overall symmetry and the arrangement of its polar bonds within the molecule. In some cases, the polarities of individual bonds may cancel out, resulting in a nonpolar molecule.
Is it true that oil is covalent and water is ionic.?
No, both oil and water are covalent compounds. Oil is made up of nonpolar covalent molecules, while water is a polar covalent molecule. Ionic compounds are typically formed between metals and nonmetals, like salt (NaCl).
Which of the following compounds should be soluble in CCL4?
Nonpolar compounds should be soluble in CCl4 since it is a nonpolar solvent. Compounds like nonpolar organic compounds or those with only nonpolar covalent bonds tend to be soluble in CCl4.
Are covalent compounds soluble in nonpolar solvents?
No, covalent compounds are typically insoluble in nonpolar solvents because they do not have significant ionic character or charges for the solvent to interact with. Nonpolar solvents are not able to disrupt the strong covalent bonds between the atoms in the compound, making them insoluble.
Can water form covalent bonds with nonpolar molecules?
No. It can't.
Why do polar covalent molecules have higher melting points than non polar covalent compounds?
They maintain their bonding far longer than nonpolar molecules can with the addition of heat energy. Remember their slightly negative ends will bind with the slightly positive ends of the adjacent molecule.
Do diatomic elements have nonpolar covalent bonds?
Yes, diatomic elements like hydrogen (H2), nitrogen (N2), and oxygen (O2) have nonpolar covalent bonds. In these molecules, the atoms share electrons equally due to the same electronegativity, resulting in nonpolar covalent bonds.
