Question

Give the major force between ethanol and water. dipole-dipole dispersion hydrogen bonding ion-ion ion-dipole

Answer 1

Answer:

HYDROGEN BONDING

Explanation:HYDROGEN BONDING is the major intermolecular force and interaction taking place when water and ethanol are mixed.

Hydrogen bond is a weak inter-molecular force of attraction which occurs when the partially charged Negative end of an oxygen atom from one oxygen molecule attracts and interacts with the partially charged Positive end of the Hydrogen atom in another Molecule, Hydrogen bonds are also known as dipole-dipole bonds.

Answer 2

Answer:

Hydrogen bond.

Explanation:

Ethanol which has general formula of CnH2n+1OH; a polar –OH group, which hydrogen bonds to water hence, makes ethanol soluble. This -OH group undergoes an intermolecular attraction with water molecules forming Hydrogen bond with the Oxygen as well as the hydrogen.

Alkanols have a trend in which solubility decreases as the CnH2n+1-alkyl group increases. This is because the alkyl group is not water-soluble (hydrophobic) hence its inability to form hydrogen bond with individual water molecules.
