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 word means different and describes how molecules are distributed in a solution?
The word you are looking for is "heterogeneous." This term describes a solution where the molecules are not evenly distributed and instead are arranged in different regions or phases within the solution.
Hydrogen bonds can form between regions of polar molecules that are?
Hydrogen bonds can form between regions of polar molecules that are partially positive and partially negative. This occurs when hydrogen atoms covalently bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine interact with neighboring atoms with a partial negative charge.
What polar molecules are attracted to water?
Polar molecules with positively charged regions, such as ammonia and alcohols like ethanol, are attracted to water due to hydrogen bonding. Additionally, polar molecules with negatively charged regions, such as acetate ions, are also attracted to water for the same reason.
What is the coordinate bonding and what is the difference between it and the covalent bonding?
Covalent bonding involves two or more atoms sharing electrons. Coordinate covalent bonding is just an attraction that molecules have for other molecules based on the asymmetrical distribution of electrons in those molecules, creating negatively charged and positively charged regions (and hence, an attraction between the negatively charged regions of one molecule and the positively charged regions of another molecule).

Gasoline and cooking oil are not amphipathic molecules why?
They do not have polar or charged regions.
What molecules have no charged regions?
Molecules that have no charged regions are called nonpolar molecules. These molecules have an equal distribution of electrical charges, meaning there are no distinct positive or negative poles. Examples include hydrocarbons like methane (CH₄) and carbon dioxide (CO₂). Nonpolar molecules typically do not interact well with polar substances like water.
Can polar molecules have regions of charge?
Not only can they, they must. At least one positively charged region and at least one negatively charged region.

The slight attractions that develop between oppositely charged regions of nearby molecules are?
van der Waals forces.
Lipis are what molecules because they have no negative and positive molecules?
Lipids are nonpolar molecules because they have a long hydrophobic tail that does not interact with water molecules. This absence of charged regions makes lipids insoluble in water.
Which of the following would be most likely to contribute to molecules experiencing intermolecular forces?
Hydrogen bonding
What polar molecules are attracted to water?
Polar molecules with positively charged regions, such as ammonia and alcohols like ethanol, are attracted to water due to hydrogen bonding. Additionally, polar molecules with negatively charged regions, such as acetate ions, are also attracted to water for the same reason.
Is fat polar?
Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
Why do nonpolar molecules not have oppositely charged ends?
Nonpolar molecule is one which electrons are shared equally in bonds. Such a molecule does not have oppositely charged ends. This is true of molecules made from two identical atoms or molecules that are symmetric, such as CCl4.
