Which molecule is most soluble in water?
propanoic acid
All the molecules contain a polar group. However, the molecule that should be most soluble in water is propanoic acid.
How do you determine the solubility of a molecule in water?
Water is a polar compound, and only “like dissolves like”. Meaning if the solute is a polar compound (in general, not intramolecular forces), then it will dissolve. You can determine the general polarity by identifying its molecular shape. If it’s symmetrical, it is non-polar.
How do you know which solute is more soluble?
Additionally, solutes will be more soluble if the molecules in the solute are smaller than the ones in the solvent. This is because it is more difficult for solvent molecules to surround bigger molecules.
How do you know which one is least soluble in water?
– To find the least soluble substance at a given temperature we follow the temperature line up and the first substance curve we hit is the least soluble. For most soluble it is the same proceedure except the last substance curve hit is the most soluble.
Which molecules are soluble in water?
Sugar, sodium chloride, and hydrophilic proteins are all substances that dissolve in water. Oils, fats, and certain organic solvents do not dissolve in water because they are hydrophobic.
Which compound is more soluble in water CH3OCH3 or CH3CH2OH?
The alcohol, CH3CH2OH, is more soluble in water since it can form a hydrogen bond to water and accept a hydrogen bond from water. The ether, CH3OCH3, can only accept a hydrogen bond from water.
How do you compare solubility?
The relative MOLAR solubility of salts (saturated solution) can be determined by comparing Ksp values. The greater the Ksp the more ions are in solution, hence the greater the molar solubility.
What makes a solvent more soluble?
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
Which molecule is least soluble in water?
The organic compound that is the least soluble in water is octane.
Which molecule has least solubility in water?
Due to lack of hydrogen bonding, alkane is least soluble inter.
How do you determine the solubility of organic molecules?
The solubility of organic molecules is often summarized by the phrase, “like dissolves like.” This means that molecules with many polar groups are more soluble in polar solvents, and molecules with few or no polar groups (i.e., nonpolar molecules) are more soluble in nonpolar solvents.
Does solubility depend on the solute or the solution?
It depends on the solution and the solute. Usually, the rule is “like” dissolves “like”. A polar solution will dissolve polar compounds and a non-polar solution will dissolve non-polar compounds. As far as I know, to find the solubility you have to determine it experimentally.
Which part of a molecule does not help to dissolve in water?
If organic compounds molecular mass is small, they have a higher possibility to dissolve in water. C-H bond is not enough polarized to make hydrogen bond because difference of electronegativity of between carbon and hydrogen is small. Therefore C-H bond are non-polar. So hydrocarbon part of molecule does not help to dissolve in water.
Are vitamins soluble or insoluble in water?
Molecular Basis for Water Solubility and Fat Solubility. Hence, vitamins are either water-soluble or fat-soluble (soluble in lipids and nonpolar compounds), depending on their molecular structures. Water-soluble vitamins have many polar groups and are hence soluble in polar solvents such as water.
