What is the structure of acetylsalicylic acid?

C₉H₈O₄
Aspirin/Formula

How many pi bonds are present in acetylsalicylic acid aspirin shown below )?

Thus, we have 5 + 2 + 6 = 13 σ bonds and 2 + 3 = 5 π bonds.

Which parts of acetylsalicylic acid are rigid which parts of acetylsalicylic acid are rigid?

groups with the atoms directly attached to them are rigid structures. All double bonded atoms are unable to rotate because the π bonds prevent them from doing so. In this sense, they are “rigid”. So the 6-membered ring with alternating C-C and C=C bonds is “rigid”.

How many pi bonds are in aspirin?

And the number of double bonds i.e. pi bonds is equal to 5 ( 2 C-O pi-bonds outside the ring and 3 C-C pi bonds inside the benzene ring. Thus, the number of sigma and pi bonds present in the structure of aspirin are 13 and 5 respectively.

How many total pi bonds are in acetylsalicylic acid?

5 pi bonds
Hence, a total of 13 sigma bonds and 5 pi bonds are present in the aspirin molecule.

What is the chemical name and formula of aspirin?

2-Acetoxybenzoic acid
Aspirin/IUPAC ID

What parts of acetylsalicylic acid are free to rotate?

In acetyl-salicylic acid, there are two kinds of bonds namely the carbon-carbon within the aromatic ring and carbon-oxygen bond. Hence these are the only two rigid bonds that can only be rotated if they are broken. The carbon-oxygen bond and the carbon-carbon bond in the ring are evident in the image attached.

How many sigma bonds are present in aspirin?

Thus, the number of sigma and pi bonds present in the structure of aspirin are 13 and 5 respectively.

How many pi bonds are present in acetylsalicylic acid?

This problem has been solved! The structure of acetylsalicylic acid (aspirin) is shown below (Figure 1). You may want to reference Section 10.7 while completing this problem How many pi bonds are present in acetylsalicylic acid?

How is acetylsalicylic acid dissolved in aspirin?

In this purification method, the crude aspirin will be dissolved in a small amount of warm ethanol. Water will then be added and the solution will be cooled slowly and then chilled. The acetylsalicylic acid will recrystallize, and the solid impurities (unreacted salicylic acid) should remain dissolved in the solution.

How is aspirin made in the bloodstream?

It is then absorbed into the bloodstream. Aspirin can be made by reacting salicylic acid with acetic acid in the presence of an acid catalyst. The phenol group on the salicylic acid forms an ester with the carboxyl group on the acetic acid. However, this reaction is slow and has a relatively low yield.

What are the antiinflammatory properties of aspirin?

Aspirin. Aspirin is an orally administered non-steroidal antiinflammatory agent. Acetylsalicylic acid binds to and acetylates serine residues in cyclooxygenases, resulting in decreased synthesis of prostaglandin, platelet aggregation, and inflammation. This agent exhibits analgesic, antipyretic, and anticoagulant properties.
