Which of the following compounds is most polar caffeine ibuprofen acetaminophen aspirin?
Ibuprofen is least polar and Caffeine is most polar. caffeine contains two amide groups, two amine groups and an alkene group.
Is ibuprofen polar or nonpolar?
Ibuprofen has a polar end, the carboxylic acid group, which can act both as a hydrogen donor and a hydrogen acceptor establishing moderate to strong interactions with other polar molecules. The other part of ibuprofen is non-polar.
Is caffeine less polar than aspirin?
Acetaminophen has a phenol and amide function group, but caffeine has multiple amide functional groups; therefore, acetaminophen is more polar than aspirin and less polar than caffeine.
Why is aspirin the least polar?
1 Expert Answer The difference between the two is that aspirin is salicylic acid with the free OH of salicylic acid having been esterified. Both compounds still have the -COOH group. So, it comes down to comparing -OH to -OC=OCH3. The -OH group is more polar than the ester so salicylic acid is more polar than aspirin.
What parts of caffeine are polar?
Yes, caffeine is a polar molecule. The Oxygen and Nitrogen molecules have a stronger polarity than Carbon, allowing them to slightly pull the electrons towards them in their covalent bond. This will give those atoms a slightly negative charge while giving the Carbon a positive charge.
What is the solubility of acetaminophen?
Water
AcetoneAlcohol
Acetaminophen/Soluble in
Is paracetamol polar or nonpolar?
Paracetamol has a very low solubility in nonpolar and chlorinated hydrocarbons such as toluene and carbon tetrachloride whereas the solubility is very high in solvents of medium polarity such as N,N-dimethylformamide, dimethyl sulfoxide, and diethylamine.
Is caffeine polar or nonpolar compound?
Why is caffeine most polar?
Caffeine is water soluble, so it is a polar compound. If you’re looking for a more chemically accurate answer, the reason in the caffeine molecule is because nitrogen and oxygen are more polar than carbon, which means they can bring covalent electrons closer to their counterparts.
Is aspirin a polar?
The aspirin molecule is made up of a benzene ring, a carboxyl group, and an ester. It has both polar and non-polar components.
How do we know caffeine is polar?
Yes, caffeine is a polar molecule. The Oxygen and Nitrogen molecules have a stronger polarity than Carbon, allowing them to slightly pull the electrons towards them in their covalent bond. This will give those atoms a slightly negative charge while giving the Carbon a positive charge. Caffeine is water soluble.
Is caffeine a tertiary amine?
Caffeine is built up of two carbonyl groups and 4 tertiary amines.
Which is more polar acetaminophen or ibuprofen?
Acetaminophen has two hydrogen bonds and one dipole-dipole making it more polar than Aspirin, Phenacetin, and Ibuprofen. Lastly, caffeine has the lowest R F value because it has the capability to ionize and form a hydrogen bond with the lone pair of electrons on the nitrogen.
Which is more polar paracetamol or caffeine?
The more polar a molecule, the more it will be attracted to the mobile phase, hence will travel through the column faster, hence shorter retention time. So based on this alone, Paracetamol is more polar than caffeine. Is paracetamol more polar than aspirin?
Why is the chemical formula for acetaminophen polar?
Acetaminophen And It’s Polarity. The chemical formula for acetaminophen is C8H9NO2. Because of the variation of electronegativity, the unshared electron pairs, and the lack of “lines of symmetry”, acetaminophen is a polar molecule. Since acetaminophen has no lines of symmetry, it must be polar.
Why does caffeine have a lower your f value than acetaminophen?
Lastly, caffeine has the lowest R F value because it has the capability to ionize and form a hydrogen bond with the lone pair of electrons on the nitrogen. Simply so, is acetaminophen a polar?
