What wavelength does acetaminophen absorb at?
3. Results and discussion. In the UV–vis spectrum, Paracetamol exhibits maximum absorbance (λmax) at 243 nm in methanol, while Aspirin and Caffeine have λmax in proximity to 237 nm and 273 nm, respectively.
What functional groups are in acetaminophen?
- The functional groups in acetaminophen are phenol, aromatic ring, and amide.
- Explanation:
- The structure of acetaminophen is (in figure)
- The group at the top of the molecule is a hydroxyl group.
- But an –OH group attached to a benzene ring has special properties.
- The six-membered ring is an aromatic ring.
What is IR spectrum range?
The typical IR absorption range for covalent bonds is 600 – 4000 cm-1. The graph shows the regions of the spectrum where the following types of bonds normally absorb. For example a sharp band around 2200-2400 cm-1 would indicate the possible presence of a C-N or a C-C triple bond.
What is AMAX chemistry?
Illustrated Glossary of Organic Chemistry – Lambda max. Lambda max (λmax): The wavelength at which a substance has its strongest photon absorption (highest point along the spectrum’s y-axis). This ultraviolet-visible spectrum for lycopene has λmax = 471 nm.
What does not show up on IR spectrum?
Alkanes show two sets of peaks in the IR spectrum. Alkanes contain two kinds of bonds: C-C bonds and C-H bonds. C-C bonds are usually nonpolar and usually do not show up as peaks in the IR spectrum. C-H bonds are not very polar and do not give rise to strong peaks in the IR spectrum.
What functional groups are in ketoprofen?
An oxo monocarboxylic acid that consists of propionic acid substituted by a 3-benzoylphenyl group at position 2. Ketoprofen is one of the propionic acid class of nonsteroidal anti-inflammatory drugs (NSAID) with analgesic and antipyretic effects.
What type of reaction produces acetaminophen?
Reactions of Paracetamol (acetaminophen) Hydrolysis (reaction with water) of amides in acidic solution produces an amine and a carboxylic acid.
