The especially strong intermolecular forces in ethanol are a result of a special class of dipole-dipole forces called hydrogen bonds. ... A hydrogen bond is the attraction between a hydrogen bonded to a highly electronegative atom and a lone electron pair on a fluorine, oxygen, or nitrogen atom.

Does Ethanal have hydrogen bonding?

Firstly, dipole-dipole forces can form between ethanal and water because of the electronegativity difference between O and H in ethanal. Although ethanal-ethanal-bond is probably weak due to your argument of "adjacent heteroatoms", there is still water to which ethanal can form a hydrogen-bond.

What bonding does Ethanal have?

Ethanal is commonly known as acetaldehyde. It is an aldehyde molecule containing two carbon atoms. Ethanal has five single bonds and one carbon-oxygen double bond.
