Concept explainers

UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

Question

-1
An acidic liquid has a broad band at 3300 cm and
a sharp band at 1710 cm-¹ in the infrared spectrum.
One mole of this unknown reacts with one mole of
NaOH. The ¹H NMR spectrum shows three
peaks in the ratio 2 : 2:1. Microanalysis gave C,
33.2%; H, 4.6%; C1, 32.7 %.
Part A
Deduce the structure of the unknown.
Spell out the full name of the compound.

The reaction of an unknown with ethanol in the presence
of a small amount of H₂SO4 leads to a compound that
smells distinctly like rum. The protondecoupled ¹³C
NMR spectrum of the product is as shown in the figure
(* =solvent). (Figure 1)

0.9583 g of sample was dissolved in 80 mL of xylene and extracted with three 15 mL quantities of water. The combined aqueous extracts were diluted to 50.0 mL and then shaken with 10 mL toluene. The toluene was then discarded. The absorbance of the aqueous solution when measured in a 1cm path length cell was 0.134 at 278 nm.Calculate the free chlorampenicol content of the sample in ppm, given A(1%, 1cm) = 298 at 278 nm.
