What are the two main functional groups present in salicylic acid?

What two functional groups are present in salicylic acid?

Salicylic acid (2-hydroxybenzoic acid) consists of a benzene ring to which 2 groups adhere, carboxyl group and hydroxyl groupare attached. We don’t normally consider benzene as a functional group, so hydroxy and carboxyl are what count.

What are the three functional groups of salicylic acid?

Functional groups of salicylic acid. Violet = phenol; green = carboxylic acid; blue = phenyl.

What are the 2 functional groups?

  What are the main cash crops in the Andes region?

Some of the important functional groups in biological molecules include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate and sulfhydryl groups. These groups play an important role in the formation of molecules such as DNA, proteins, carbohydrates, and lipids.

What functional groups are present in aspirin?

The common name of aspirin is acetylsalicylic acid and its IUPAC name is 2-acetoxybenzoic acid. Between the ester and carboxylic acid functional groups The highest priority functional group is carboxylic acid. Hence, in aspirin, the carboxylic acid is the major functional group. Therefore, B, -COOH is the correct option.

Is salicylic acid primary or tertiary?

The salicylic acid pathway is one of the primary defense pathways in plants, is ubiquitous in vascular plants, and plays a role in rapid adaptation to dynamic abiotic and biotic stress. … These secondary the effects can both directly affect those attacking plants and mediate indirect interactions between herbivores and pathogens.

Which functional group is not present in the salicylic acid reagent?

The structures look quite similar. Both have a benzene ring carrying two groups on adjacent carbon atoms. In both of them, one of the groups is a carboxylic acid group. But salicylic acid carries with it phenolic group while aspirin does not.

What functional groups are in aspirin and salicylic acid?

Aspirin (acetylsalicylic acid) has three groups:

  • carboxylic acid functional group (R-COOH)
  • ester functional group (RO-CO-R ‘)
  • aromatic group (benzene ring)
  Where are the most Greek ruins

Is salicylic acid polar?

The -OH group is more polar than the ester, so salicylic acid is more polar than aspirin.

What is an ether functional group?

The ether functional group consists of an oxygen atom that forms single bonds with two carbon atoms. Figure 4.4. 4: Ethers. Ethers are good solvents for other organic compounds due to their low reactivity. They easily dissolve non-polar particles.

Which functional group in salicylic acid can act as a nucleophile?

This time hydroxyl group Salicylic acid acts as a nucleophile by attacking the carbonyl group of acetic anhydride and replacing one of the acetyl groups.

Does salicylic acid have an ester functional group?

Note that salicylic acid does an organic acid functional groupand an alcohol group on an aromatic hydrocarbon ring. Acetylsalicylic acid retains the functionality of an organic acid, but the alcohol has been modified to form an ester group. … All esters share the relationship shown above (right).

What other important functional group does salicylic acid contain?

Salicylic acid does OH groupand aspirin has an ester.

What functional group in salicylic acid reacts with acetic anhydride to form an ester?

-OH To produce acetylsalicylic acid, -OH group salicylic acid reacts with acetic acid to form ester and water.

What type of organic functional group does the alcohol group in salicylic acid get during the reaction?

  What is the 4 main screw on the Chevy 350

ester When an alcohol reacts with a carboxylic acid in the presence of an acid catalyst, the functional groups combine in a condensation reaction to form ester and water: Page 3 As a result of the reaction of the phenol group of salicylic acid with acetic acid, an ester group (which is not acidic) is formed and the resulting …

What are the two functional groups in methyl salicylate?

In methyl salicylate (left), the benzene ring is substituted with two functional groups, a hydroxyl group (-OH) and an ester group (-COOCH3).

What is the functional group of acetic acid?

All organic acids, such as acetic acid, contain a functional group called carboxyl group. The carboxyl group contains C = O. carbonyl group, wherein the carbon atom is also bonded to the hydroxyl group (-OH). A carboxylic acid is an organic compound that contains a carboxylic acid functional group.

What functional groups are in acetic anhydride?

Generally, the synthesis of acetic anhydride involves a dehydration reaction two carboxylic acid functional groups. Acetic anhydride can be used for various purposes such as the production of aspirin and cellulose acetate for plastic products.

What reacts with salicylic acid?

However, salicylic acid also has an electrophilic carbon atom as part of its carboxylic acid functional group. Thus, salicylic acid can react with nucleophilic molecules such as methanol in addition to reacting with electrophilic molecules such as acetic anhydride.
