What kinds of intermolecular forces are present in a mixture of ethanol (ch3ch2oh) and water?

Answer;

Dipole-dipole and hydrogen bonding

Explanation; A solution of water and ethanol contains the dipole-dipole forces and hydrogen bonds as the intermolecular forces between molecules. Hydrogen bonding is a type of interactions between molecules that occurs when a partially negative atom such as oxygen end of one of the molecules is attracted to a partially positive hydrogen end of another molecule. Dipole-dipole forces results from the unsymmetrical distribution of electrons, thus the polarity does not balance, thus resulting to a dipole attraction between molecules.
