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.
What type of molecule is ibuprofen?
Ibuprofen is a monocarboxylic acid that is propionic acid in which one of the hydrogens at position 2 is substituted by a 4-(2-methylpropyl)phenyl group.

Aspirin is a polar molecule with dipole-dipole attraction bonds and an -OH (hydroxyl) segment as part of a carboxylic acid group.
How many polar covalent bonds are in ibuprofen?
Unlike acetaminophen with three polar groups, ibuprofen only has one polar group, the carboxylic acid functional group, making this over-the-counter painkiller somewhat soluble in water and soluble in organic solvents.
Is ibuprofen an aromatic compound?
Question 2 What functional groups does ibuprofen have? A carboxylic acid and an aromatic ring.
What is the solubility of ibuprofen?
Ibuprofen is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide, which should be purged with an inert gas. The solubility of (±)-ibuprofen in these solvents is approximately 60, 50, and 45 mg/ml, respectively.Is ibuprofen more polar than aspirin?
Based on the rate of migration, one can conclude that the acetaminophen, aspirin and caffeine are polar and prefer to be on the stationary phase while the naproxen sodium, unknown and ibuprofen are less polar with weak bonds.
Is ibuprofen a chiral molecule?As is the case with numerous other drugs, Ibuprofen is a chiral compound. The human body with its numerous homochiral compounds will interact with each racemic drug differently and metabolize each enantiomer by a separate pathway to generate a different pharmacokinetic and pharmacodynamic activity.
Article first time published onDoes ibuprofen have active metabolites?
Ibuprofen is almost completely metabolized, with little to no unchanged drug found in the urine [1,9,12]. The primary route of elimination is oxidative metabolism by CYP enzymes to inactive metabolites (Fig. 1).
Is ibuprofen an optical isomer?
Ibuprofen (IBU) is a non-steroidal anti-inflammatory drug exhibiting optical isomerism. Only the racemate is in clinical use. In in vitro studies it has been demonstrated that only the S(+)-enantiomer inhibits the PG synthetase system.
Is Tylenol polar?
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.
Is caffeine a polar molecule?
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 salicylic acid or aspirin more polar?
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.
Is ibuprofen a benzene?
A Non-Steroid Anti-Inflammatory Drug This simply means the molecule contains an aryl group (the benzene ring), joined to a carboxylic acid derived from propane (3 carbons). The most well known of these drugs is ibuprofen.
Is ibuprofen an organic molecule?
Structure for FDB022743 (Ibuprofen) Belongs to the class of organic compounds known as phenylpropanoic acids. Phenylpropanoic acids are compounds with a structure containing a benzene ring conjugated to a propanoic acid.
What is the pKa of ibuprofen?
Ibuprofen has a pKa of 4.43±0.03 and an n-octanol/water partition coefficient of 11.7 at pH 7.4. The chemical name for ibuprofen is (±)-2-(p-isobutylphenyl) propionic acid. The molecular weight of ibuprofen is 206.28.
Is ibuprofen a homogeneous or heterogeneous mixture?

What bonds does ibuprofen have?
The design of Ibuprofen is two 2-methylpropylbenzene put together. There are 3 de localized pi orbitals. The negative region of the medicine is where it bonds with oxygen. The positive side is the side where Oxygen bonds with Hydrogen[specifically the Hydrogen].
What is the solubility of racemic ibuprofen?
White to almost white, very fine crystalline powder with a high volume. In the literature the solubility of Ibuprofen (acid) in distilled water is reported to be less than 0.1%. The solubility of Ibuprofen Lysinate is 1:5, or about 17% (Ibuprofen, K. D. Rainsford, Taylor & Francis Ltd.
Is Motrin an Nsaid drug?
MOTRIN® is classified as an NSAID, a non-steroidal anti-inflammatory drug, and contains ibuprofen[i]. Ibuprofen is used to relieve pain and reduce fever.
Why is ibuprofen slightly soluble in water?
Unlike acetaminophen with three polar groups, ibuprofen only has one polar group, the carboxylic acid functional group, making this over-the-counter painkiller somewhat soluble in water and soluble in …
Which compound is more polar caffeine or ibuprofen?
Ibuprofen is least polar and Caffeine is most polar. caffeine contains two amide groups, two amine groups and an alkene group.
How do you determine polarity?
The terms “polar” and “nonpolar” usually refer to covalent bonds. To determine the polarity of a covalent bond using numerical means, find the difference between the electronegativity of the atoms; if the result is between 0.4 and 1.7, then, generally, the bond is polar covalent.
Is paracetamol more polar than aspirin?
Acetaminophen has two hydrogen bonds and one dipole-dipole making it more polar than Aspirin, Phenacetin, and Ibuprofen.
Is ibuprofen soluble in acetone?
Solubility (g/100 g of solvent): 1,4-dioxane: 9 (25°C) [Ref.] acetone: 58.76 (10°C) [Ref.]
Is ibuprofen poorly soluble?
Ibuprofen is badly water soluble drug and distilled water was used as dissolution medium. The amount of drug was measured form the absorbance of UV spectrophotometer at 214nm.
Is ibuprofen soluble in methanol?
The solubility of ibuprofen in pure solvents decreased in the following order: DMSO > methanol > ethanol > isopropanol > n-propanol > PEG-200 > PG > water. The addition of ibuprofen to n-propanol-water mixtures, isopropanol-water mixtures and DMSO-water mixtures resulted in phase-separation.
Is aspirin a chiral?
Explanation: Aspirin, pictured, has no chiral centres and planar symmetry. It cannot support optical isomerism.
Is ibuprofen an aspirin derivative?
While aspirin and ibuprofen are both NSAIDs, they are made from different key ingredients. Aspirin is made out of salicylic acid, and ibuprofen is made from propionic acid.
