What are the functional groups found in aspirin?
There are three functional groups found in aspirin:
- Carboxylic acid consists of a carbonyl group (CO) and a hydroxyl group (OH). It’s also referred to as the R-COOH group.
- Ester consists of a carbonyl group (CO) bound to an oxygen group.
- The aromatic group (benzene) is the ring you see in aspirin.
What part of aspirin is polar?
For this reason aspirin is not likely to be addictive due to certain features in its molecular structure. Aspirin is a polar molecule with dipole-dipole attraction bonds and an -OH (hydroxyl) segment as part of a carboxylic acid group.
Which of the following functional groups is are not present in aspirin?
We do have a benzene ring, but it is not attached to a hydroxyl (OH) substituent. Therefore, we do not have a phenol functional group. A ketone functional group is Rx(CO)Ry R x ( C O ) R y , which is also not present in aspirin.
Is aspirin a polar solute?
The aspirin molecule is made up of a benzene ring, a carboxyl group, and an ester. It has both polar and non-polar components.
What are the two important functional groups in aspirin?
(ester). The common name of aspirin is acetylsalicylic acid and its IUPAC name is 2-Acetoxybenzoic acid. Between ester and carboxylic acid functional groups the highest priority functional group is carboxylic acid. Hence, in aspirin carboxylic acid is the principal functional group.
Why is aspirin so polar?
Aspirin has the third highest R F value with two dipole-dipole forces and one hydrogen bond, almost identical to the R F value of Phenacetin. Acetaminophen has two hydrogen bonds and one dipole-dipole making it more polar than Aspirin, Phenacetin, and Ibuprofen.
Is caffeine more 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 more soluble in water that contains 10% NaOH than it is in pure water?
Question: Question 3 1 pts Why is aspirin more soluble in water that contains 10% NaOH than it is in pure water? Because NaOH is nonpolar. Because aspirin is very polar. Because its carboxylic acid group reacts with NaOH to form a salt.
What are the functional groups present in aspirin?
What functional groups are present in aspirin? As you can see- carboxylic acid and ester groups are present. You can also see a benzene ring on the left side.
What is the structure of aspirin acetylsalicylic acid?
Structure of Aspirin (acetylsalicylic acid) 1 carboxylic acid functional group (R-COOH) 2 ester functional group (R-O-CO-R’) 3 aromatic group (benzene ring)
What makes ASA a polar or non polar molecule?
Whether the molecule behaves more like a polar or non-polar molecule will depend on which region is more significant. Acetylsalicylic acid (ASA) has two polar regions, a carboxyl group (giving it it’s acidic property) and a ester group. However, these two groups are attached to a benzene ring which is a non-polar 6 carbon hydrocarbon.
Which is the correct equilibrium position for aspirin?
the equilibrium position lies well to the left, favouring molecular aspirin. Aspirin is only slightly soluble in water and acidic solutions such as is present in the stomach. Aspirin contains polar functional groups which can form hydrogen bonds with polar water molecules.
