Acoustic, volumetric and spectroscopic investigations in binary mixtures of formamide/N-methylformamide + 2-chloroethanol at various temperatures

The hydrogen bonding occurs between oxygen atom of C═O group of formamide and N-methylformamide molecules and hydrogen atom of the ―OH group of 2-chloroethanol molecule in FA + 2-CletOH and NMF + 2-CletOH liquid mixtures, as shown below.
