The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound exhibits strong, broad absorption between 3300 and 3500 and at 1050 cm-1. 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 cm-1. 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 h. amine i. aldehyde or ketone j. carboxylic acid k. ester I. nitrile e. arene f. alcohol g. ether
