Why does alchohol dissolve in water?

Answer 1

Alcohols are soluble in water because of the presence of OH functional group in them. This increases its tendency to form hydrogen bond with water. So alcohol can dissolve in water because both can form hydrogen bonds with each other.

Answer 2

A substance's solubility in a particular solvent is governed by the types of intermolecular forces that each can form. The general rule is "like dissolves like." Water is polar, and it is capable of forming hydrogen bonds. Therefore, substances which are polar and can form hydrogen bonds are soluble in water. Those which cannot, on the other hand, are insoluble.

Answer 3

Because it does have a higher polarity compared with ethane. And the hydrogen attached to oxygen of ethanol makes a hydrogen bond with the oxygen of water. So based on "like dissolved like", ethanol is much like water, so it is soluble to any proportion in the water. But alcohols of higher carbon as the number of their carbon increases, they change more to be like an oil(lipid), so the solubility decreases.

Answer 4

There is actually opposing trends when it comes to the solubility of alcohol in water. Alcohol contains a carbon chain and an OH group. Since water is polar, it attracts the polar OH group and repels the non-polar carbon chain. Therefore, the solubility of alcohol in water depends on which force is stronger.

Answer 5

It doesn't dissolve in water. It happens that the alcohol molecules and the water molecules sort of 'fit' together, taking up less space then the two of them do alone. It is sort of like taking a jar of marbles and a jar of sand and mixing them together. They won't take up two jar fulls of space any more.

Answer 6

Because alcohols in O-H groups can be dissociated in aqueous solution to give O- H+ ions, they can easily be hydrated (dissolved)

Glycerin

Sucrose

Ethanol

Methanol

2-Propanol

Answer 7

Alcohol dissolves in water because the molecules of alcohol and water are polar, with positively and negatively charged ends. This helps to form hydrogen bonds between the alcohol and water molecules, allowing them to mix and dissolve in each other.

Answer 8

Alcohols have that -OH stuck on them ... that makes them polar (one part of the molecule is charged compared to the rest)

and water is the ultimate polar solvent.
