The lifetime of the H-bond, 2.1 ps, is consistent with experimental data, with short time librations on the order of femtoseconds. WebPhenol can make hydrogen bonds due to -OH bond. But due to large phenyl group, phenol does not dissolve in water. Aldehyde and Ketone Aldehyde and ketone which have less molecular mass, will dissolve in water. Formaldehyde, Ethanal, butanal are soluble aldehydes. Benzaldehyde is insoluble in water. john creswell research design 4th edition pdf
