Is ethanol more soluble in water or methanol?
Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount….Alcohol solubility chart.
| Name | Formula | Solubility |
|---|---|---|
| Methanol | CH3OH | miscible |
| Ethanol | C2H5OH | miscible |
| Propanol | C3H7OH | miscible |
| Butanol | C4H9OH | 0.11 |
Why is ethanol highly soluble in water?
Ethanol is an alcohol that is soluble in water. This is because of the hydroxyl group (−OH) in the ethanol that is able to form hydrogen bonds with the water (H2O) molecules. The intermolecular hydrogen bonding is very high in the ethanol that is why it is soluble.
Why is methanol more soluble than ethanol?
For alcohols, it is known that as the number of carbon chain or skeleton increases the lesser its solubility in that polar solvent. Ethanol has one extra carbon in its skeleton than methanol. Hence, methanol will be more soluble in water than ethanol.
Why is methanol less soluble than ethanol?
Hydrogen Bonding of Methanol The longer the carbon chain in an alcohol is, the lower the solubility in polar solvents and the higher the solubility in nonpolar solvents.
Why is ethanol so soluble?
Ethanol is soluble in water primarily because of the presence of -OH group that allows or enables it to form hydrogen bonds with water molecules. In other words, ethanol is soluble in water because it is a polar solvent.
Why does methanol evaporate faster than ethanol?
Methanol has the higher vapor pressure because its molecules are smaller than those of ethanol, and so its intermolecular forces are less than ethanol’s. Methanol has the higher vapor pressure because its molecular weight is less than ethanol and so its intermolecular forces are less than ethanol’s.
