Intermolecular interactions 38 Hyarogen bonsing Consider the molecule shown below eamplully. Please count the total number of a bonds present in the moleculo. i) Number of bonds in the molecule: ii) Circle all the H-bond donors in the molecule iii) How many hydrogen bond acceptors are present on the molecule? iv) Molecule A and Molecule B have aimost equivalent molecular weight. Examine both structures and Circle the molecule that is expected to have the higher boiling point. Justify your elaim with one or two brief sentences. Propose two possible hydrogen-bonding interactions between: i) 2 molecules of lactic acid; ii) isopropanol, the secondary alcohol with formula C3H7OH. Rank the following sequence on molecules in order of boiling points. (Lowest b.p =1). i) iii) IV)
