Large molecules are generally less soluble in water compared to smaller molecules. This decreased solubility is often due to their size and complexity, which can hinder their ability to interact with water molecules effectively. Additionally, many large molecules, such as proteins or polymers, may have hydrophobic regions that further reduce their solubility in aqueous environments. However, the solubility also depends on the chemical structure and functional groups present in the molecule.
Sugar is more soluble in water than caffeine. Sugar molecules are polar and can form hydrogen bonds with water molecules, allowing them to dissolve easily. Caffeine is less soluble in water due to its nonpolar nature, making it less likely to interact with water molecules.
In general, cations are soluble in water because they form positive ions that can attract the negatively charged oxygen atoms in water molecules. Anions can also be soluble in water depending on their size and charge, but some large and highly charged anions are less soluble due to stronger electrostatic interactions with water molecules.
Glycerophospholipids have a polar head group that interacts with water molecules, making them soluble in water. Triglycerides lack this polar head group, which makes them less soluble in water.
Ionic compounds are typically soluble in water, as they can dissociate into ions when in solution, allowing them to interact with the polar water molecules. Covalent compounds, especially those with nonpolar bonds, are generally less soluble in water.
Phospholipids and glycolipids are more soluble in water compared to triglycerides due to the presence of a hydrophilic head group, which interacts favorably with water molecules. Triglycerides, being composed mostly of hydrophobic fatty acid chains, are less soluble in water.

Ionic compounds and polar molecules are generally more soluble in water due to their ability to interact with water molecules through hydrogen bonding or ion-dipole interactions. Nonpolar molecules are typically less soluble in water because they do not have the appropriate interactions to be well-dispersed in a polar solvent like water.
Alcohols and amines are polar molecules due to the presence of hydroxyl (-OH) and amino (-NH2) groups, respectively, which can interact with water molecules through hydrogen bonding. This makes them soluble in water. Covalent compounds, on the other hand, lack polar groups that can interact favorably with water molecules, hence they are generally less soluble in water.
Phospholipids and glycolipids are more soluble in water compared to triglycerides due to the presence of a hydrophilic head group, which interacts favorably with water molecules. Triglycerides, being composed mostly of hydrophobic fatty acid chains, are less soluble in water.
Covalent bonds are generally less soluble in water compared to ionic bonds. Ionic compounds dissolve in water because of the attraction between the ions and the polar water molecules. In contrast, covalent compounds are usually nonpolar or have weaker polar bonds, making them less likely to interact with polar water molecules and dissolve.
Nickel fluoride is sparingly soluble in water, meaning only a small amount of it will dissolve. In general, fluorides tend to be less soluble in water than other compounds due to the strong attraction between the fluoride ions and the water molecules.
Propanamine is soluble in water due to its shorter carbon chain and the presence of an amino group that can form hydrogen bonds with water molecules. In contrast, heptanamine has a longer hydrophobic carbon chain, which reduces its overall polarity and ability to interact with water, making it less soluble. The balance between hydrophilic and hydrophobic regions in these molecules significantly affects their solubility in water.
Ionic solids are generally the most soluble in water because they consist of charged particles that interact favorably with the polar water molecules. When ionic compounds dissolve, the water molecules surround and separate the ions, allowing them to disperse in solution. In contrast, covalent solids typically have stronger intramolecular bonds and do not easily dissociate in water, making them less soluble.
The ions of salt are very attracted to the dipoles of water molecules, which results in more water molecules being attracted to salt ions than gas molecules. Because of this, there are less molecules capable of dissolving the gas.
