Do longer carbon chains have less soluble in water?

As carbon chain size increases, molecule become less and less water soluble.

How does carbon chain length affect solubility in water?

As the length of the carbon chain increases, the polar OH group becomes an ever smaller part of the molecule, and the molecule becomes more like a hydrocarbon. If the number of OH groups along the carbon chain increases, more solute-water hydrogen bonding is possible, and solubility generally increases.

Why does increasing carbon chain length decreases water solubility?

The acids with one to four carbon atoms are completely miscible with water. Solubility decreases as the carbon chain length increases because dipole forces become less important and dispersion forces become more predominant.

Why are large molecules less soluble?

The larger the molecules of the solute are, the larger is their molecular weight and their size. It is more difficult it is for solvent molecules to surround bigger molecules. If all of the above mentioned factors ale excluded, a general rule can be found that larger particles are generally less soluble.

Why are longer carbon chains less polar?

This is due to the combined strength of so many hydrogen bonds forming between oxygen atoms of one alcohol molecule and the hydroxy H atoms of another. The longer the carbon chain in an alcohol is, the lower the solubility in polar solvents and the higher the solubility in nonpolar solvents.

What happens to solubility of a molecule as the hydrocarbon chain increases in length?

Their –O–H groups form hydrogen-bonds with water molecules to form stabilizing interactions. As the length of the hydrocarbon chain increases, the non-polar hydrocarbon part of the molecule starts to become more important and the solubility decreases.

What makes a molecule less soluble in water?

The presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as water. This means that carbon dioxide is less soluble in water than polar molecules are.

How does solubility in water depend on the chain length of these alcohols?

As the length of the chain increases, however, the solubility of alcohols in water decreases; the molecules become more like hydrocarbons and less like water.

How does particle size affect solubility?

Decreasing the size of the particles increases the rate of dissolving. When you break up a large mass of solute into smaller pieces, you increase the surface area that is in contact with the solvent.

Why are bigger molecules more polar?

The larger the difference in electronegativity, the larger the dipole moment. The distance between the charge separation is also a deciding factor into the size of the dipole moment. The dipole moment is a measure of the polarity of the molecule.

Does increase in polarity increase solubility?

Water is polar and polar compounds like to dissolve other polar compounds. So the more polar a compound, the more soluble it is in water.
