Is Aspirin An Ester?

Aspirin is an ester which passes through the stomach unchanged before being hydrolysed by the basic medium of the intestine to form the active compound. When a carboxylic acid reacts with an alcohol (such as ethanol or a phenol), the products are water and an ester.

Is aspirin both an acid and ester?

Iron (III) ion reacts with phenols to form a purple complex. Salicylic acid contains a phenol group, but acetylsalicylic acid does not. Therefore, if you add FeCl3 to an aspirin sample and you see a purple color, it means that there is still some salicylic acid present and the sample is impure.

Is aspirin an ester or carboxylic acid?

Aspirin is both an aromatic carboxylic acid (red oval) and a phenyl ester of acetic acid (blue oval).

Why is aspirin ester?

Note that the salicylic acid has an organic acid functional group, and an alcohol group, on an aromatic hydrocarbon ring. The acetylsalicylic acid retains the organic acid functionality, but the alcohol has been modified, to form an ester group.

Is aspirin an ether?

In the case of aspirin, the ether group is a combination of a simple phenol group (OH) and acetic acid (C2H4O2). When the ether group in aspirin is hydrolyzed, acetic acid is formed, and the aspirin molecule becomes salicylic acid.

What ester is found in aspirin?

Aspirin is a trade name for acetylsalicylic acid, a common analgesic. Acetylsalicylic acid is an acetic acid ester derivative of salicylic acid.

Is aspirin a polar?

Aspirin is a polar molecule with dipole-dipole attraction bonds and an -OH (hydroxyl) segment as part of a carboxylic acid group.

Is aspirin a phenol or ester?

Aspirin is an ester which passes through the stomach unchanged before being hydrolysed by the basic medium of the intestine to form the active compound. When a carboxylic acid reacts with an alcohol (such as ethanol or a phenol), the products are water and an ester.

Is aspirin soluble in hexane?

Acetylsalicylic acid is fairly polar and not soluble in pure hexane. Ethyl acetate (CH3CO2CH2CH3) is much more polar and your compound is very soluble in pure ethyl acetate.

Is aspirin soluble in dichloromethane?

Aspirin is soluble in dichloromethane but relatively insoluble in water. Sodium hydroxide can remove an acidic hydrogen from aspirin to make a salt, sodium acetylsalicylate, which is insoluble in dichloromethane but soluble in water (Figure 3.).

Is salicylic acid an ester?

salicylic acid or 2-hydroxybenzoic acid, C6H4(OH)CO2H, a colorless, crystalline organic carboxylic acid that melts at 159°C; it is soluble in ethanol and ether but is only slightly soluble in water. This ester hydrolyzes, not in the acidic stomach, but in the alkaline intestines, releasing free salicylic acid.

What type of hydrocarbon is aspirin?

The acetylsalicylic acid in aspirin (crystals of the compound shown here) shares the pain-relief properties of the chemical salicin in willow bark. Yet most aspirin manufacturing begins with benzene, a hydrocarbon that is typically derived from petroleum products.

What functional groups Does aspirin have?

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. Therefore, the correct option is B, -COOH.

Is aspirin a compound or element?

Acetylsalicylic acid commonly known as Aspirin is a prototypical analgesic with a chemical formula C9H8O4. It is also known as aspirin or 2-Acetoxybenzoic acid. It appears as a crystalline powder which is colourless to white. Generally, it has no smell but when in moist air it acquires a smell of acetic acid.

What element is aspirin?

The chemical name of aspirin is acetylsalicylic acid. By looking at its chemical structure, you’ll see that it’s composed of three different types of atoms: carbon, hydrogen, and oxygen.
