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 cm ¹ region, accompanied by 2200 (w) and 1715 (s) cm¹ 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 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 e. arene f. alcohol g. ether h. amine i. aldehyde or ketone j. carboxylic acid k. ester I. nitrile

C8H8O produces an IR spectrum with 3063, 1686, 1646 cm signals. HNMR is a singlet at 2.6ppm (3H), and multiplet at 7.5 (5H). What is the product

Are these 1-hexanol or 2-hexanol? Please help. I can't seem to figure it out, because when compared around it seems like it could be either.

N-H bonds absorb IR radiation at very similar frequencies as O-H (alcohol) bonds. Oftentimes, they are not quite as large. Why?

Define density.  Hexane has a density of 0.659 g/mL.  How many milliliters (mL) of hexane are in 15.0 grams (g) of hexane?

The mass spectrum of an alkene, C8H16, exhibits a peak at m/z = 41. Draw two isomers that are consistent with these data.

a) which bond is present in alcohols but not alkanes? b) is this band strong or weak (in terms of spectra)? c) what is different about C=O and O-H bonds compared with C=C or C≡C bonds that show weaker signals?
