Why does ethanol dissolve in water but ethane doesn t?
Ethanol is an assymetrical, polar molecule while ethane is a symmetrical non-polar molecule. So, when ethanol dissolves, hydrogen bonds between water molecules are broken, as are the hydrogen bonds between the molecules of ethanol and are reformed between the molecules of water and ethanol.
Why does ethanol dissolve easily in water?
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 ethane not dissolve in water?
No, ethane will not form a hydrogen bond, or ionic bond with water or any other polar molecule because it is nonpolar. Ethane does not have any partial positive or negative charges.

How does ethanol dissolve?
Ethanol is a very polar molecule due to its hydroxyl (OH) group, with the high electronegativity of oxygen allowing hydrogen bonding to take place with other molecules. Ethanol therefore attracts non-polar molecules. Thus, ethanol can dissolve both polar and non-polar substances.
Why is ethanol soluble in water polarity?
Because both the ethanol and the water are molecular substances with O−H bonds, the attractions broken between water molecules and the attractions broken between ethanol molecules are hydrogen bonds. The attractions that form between the ethanol and water molecules are also hydrogen bonds (Figure below).
Is ethene polar or nonpolar?
C2H4 C 2 H 4 is a type of alkene whose IUPAC name is Ethene and its common name is Ethylene. The hydrocarbons are mostly non-polar in nature because the electronegativity difference is not large between the carbon and hydrogen.
Why is ethanol soluble in water intermolecular forces?
The intermolecular hydrogen bonding is very high in the ethanol that is why it is soluble. The second reason is that ethanol is a polar molecular hydrocarbon due to the high electronegativity of the oxygen atom and due to this it is soluble in water.
Why ethanol is soluble in water but not chloroethane?
Explanation: Chloroethane is C2H5Cl , when when dissolved in water H2O , forms “dipole-dipole forces” between the two species of molecules. The OH group of ethanol is extremely polar and hence forms hydrogen bonding with the extremely polar water molecules. Therefore, ethanol is more soluble in water than chloroethane.
