Between formula or Lewis m name structure compound? O yes ammonia NH O yes D no O yes N-chloromethylamineHC NC no yes yes no methanol IH Check Explanation Type here to searchExplanation / Answer
Hydrogen bonding occurs in all molecules that have hydrogen attached to electronegative atoms, that tend to polarize the heteratom - hydrogen bond towards itself, depriving the hydrogen of electron-density, making it seek out electron-rich atoms from within the same molecule or from other molecules in the medium to satiate its electron-density.
Thus, all the given molecules possess hydrogen bonding between molecules of the same compound. This is via the hydrogens attached to N in ammonia (the only other atom), the one attached to N in chloromethylamine and the one attached to the oxygen in methanol.
Also, for H-bonding to occur with a certain molecule, it should have an electronegative atom that possesses unhindered lone pair of electrons to donate reversibly to the electron-deficient hydrogens in the medium. Such an atom in water is the oxygen which possesses two lone pairs, making it accept two hydrogens for hydrogen-bonding interaction. Since, all the given molecules have tendency to form-hydrogen bonding, they will do so with water also. Moreover, the hydrogens of water will also form hydrogen bondings with the heteroatoms in the given molecules, because of their lone pair(s).
