Comment on solubility

Solubility of Undecan-1-ol

Undecan-1-ol, a long-chain fatty alcohol with the chemical formula C11H24O, shows unique solubility characteristics due to its structure. It is primarily classified as an alcohol, which influences its interactions with water and other solvents.

Solubility in Water

Undecan-1-ol exhibits limited solubility in water. This is typical for long-chain alcohols, as the hydrophobic hydrocarbon tail outweighs the hydrophilic hydroxyl group. Here are some key points:

  • The solubility decreases as the carbon chain length increases; thus, undecan-1-ol is less soluble than its shorter counterparts.
  • At room temperature, it can dissolve in approximately 0.1 g per 100 mL of water.
  • The limit of solubility may also vary with temperature; heating the water might enhance dissolution slightly.

Solubility in Organic Solvents

In contrast, undecan-1-ol is quite soluble in organic solvents. Important observations include:

  • It readily dissolves in non-polar organic solvents such as hexane and ether due to its compatible hydrophobic nature.
  • Solvents that can form hydrogen bonds, like ethanol or acetone, can also solvate this alcohol effectively.

In summary, the solubility profile of undecan-1-ol showcases the balance between its hydrophobic and hydrophilic characteristics, leading to limited water solubility but good solubility in organic solvents. Understanding these properties is vital for applications in various fields, including pharmaceuticals and chemical manufacturing.
