A student has acquired an IR spectra of an unknown six-carbon molecule and has determined that it is either 2-hexyne, 1-
hexyne, or 1-hexene. How can the student use their knowledge of IR spectroscopy to determine the identity of the molecule? In
your answer, clearly specify what regions of the IR spectrum the student should look at and what bonds are responsible for the
absorption bands you indicate.
What IR frequencies would enable a chemist to
distinguish between these molecules?

- The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound containing no nitrogen exhibits strong, broad absorption across the 2500-3300 cm³¹ region, accompanied by 2200 (w) and 1715 (s) cm-¹ bands. Relative absorption intensity: (s)=strong, (m)=medium, (w)=weak. What functional class(es) does the compound belong to? List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm³¹. The functional class(es) of this compound is(are) . (Enter letters from the table below, in any order, with no spaces or commas.) a. alkane (List only if no other functional class applies.) b. alkene c. terminal alkyne d. internal alkyne e. arene f. alcohol g. ether h. amine i. aldehyde or ketone j.carboxylic acid k. ester I. nitrilearrow_forwardWhy is this the correct spectra for these molecules.
