Aspirin is the brand name for acetylsalicylic acid, which is the common name for 2-(acetyloxy)benzoic acid. This compound looks like this: Show
 In a single bond, you have a single#sigma# bond. In a double bond, there is one#pi# bond in addition to the single#sigma# bond that constituted the single bond. Thus, if we treat each double bond as a single bond on this structure, we count up the #sigma# bonds as:
Then, in accounting for the particular bonds that are double bonds, the remaining #pi# bonds are from:
Thus, we have 5 + 2 + 6 = 13#\mathbf(sigma)# bonds and 2 + 3 = 5#\mathbf(pi)# bonds. Video TranscriptDear students, this is the structure of acetyl celcilic acid acetalilic acid known as a sperano. In this we have to say how many pi ones and how many simmons are present. So let us see a number of 1 number of pi bonds. Here we have 1234 and 5 they're having 5 pi bonds, then coming to sigma bonds, because each double 1 has a pi bond. So here we are having 5 dollar ones. Therefore, 5 pi ones now coming to sigma 1 in between o and 1 sigma 11234567891011121314.14. Here, 317, here c, h, 1181920 and 21. So sigma bones are 21 point now. The third point is what parts of the molecular free to rotate. We know the single bond, the rotation. The parts which are associated with single bond are free to rotate parts associated with single bond or free to rotate. Now parts as with double bond or wing are rigid. Parts associated with associated with double bond or rings are not free to rotate, so they are rigid. Poi hope you understood. How many sigma/pi bonds are in the aspirin structure?Answer Verified Hint First of all, you should know the structure of the aspirin and then, identify the number of single bonds i.e. sigma bonds present in it and the number of double bonds i.e. pi bonds present in it , you will get your answer. Now solve it. Complete answer: From the structure, we can see that the number of single bonds i.e. sigma bonds is equal to 13 ( 5 C-O bonds, 2 C-C bonds outside the benzene ring and 6 C-C bonds within the benzene ring) 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. Note: In case of the sigma bond, the orbitals overlap end to end and the extent of overlapping is large as compared to the sidewise overlapping in case of the pi-bonds. So, therefore, sigma bond is a strong bond and pi-bond is a weak bond. Thus, the number of sigma and pi bonds present in the structure of aspirin are 13 and 5 respectively. Also, How many bonds are in acetylsalicylic acid? Chemical Structure Description The aspirin molecule contains a total of 21 bond(s) There are 13 non-H bond(s), 8 multiple bond(s), 3 rotatable
bond(s), 2 double bond(s), 6 aromatic bond(s), 1 six-membered ring(s), 1 carboxylic acid(s) (aromatic), 1 ester(s) (aliphatic) and 1 hydroxyl group(s). People Ask, How do you find the number of pi bonds? Calculation of π-bonds and double bonds (P): where, X = number of carbon atoms; Y = number of hydrogen atoms and P = number of π bonds/double bonds. E.g.: In C176H250, X = 176, Y = 250, therefore P = (2 x 176 – 250)/2 +1 = 51 + 1 = 52 number
of π bonds or double bonds. Similar QuestionsWhich bonds in acetylsalicylic acid are rigid?So the 6-membered ring with alternating C-C and C=C bonds is “rigid”. The C=O. carbon atoms and the C and O atoms directly attached to them form two more “rigid” groups. How many sigma and pi bonds are in each compound?In general, single bonds between atoms are always sigma bonds. Double bonds are comprised of one sigma and one pi bond. Triple bonds are comprised of one sigma bond and two pi bonds.

In 2014, Prestige Brands signed an agreement with Insight to acquire the company; it was Prestige Brand’s largest acquisition to that point. How many bonds does sodium have?A sodium atom can only form one ionic bond, because it only has one electron in its outer shell to donate. 4. The reason a bond is formed between chloride ions and sodium ions is because an electron has been transferred between them. 5. How is NaCl an ionic bond?Sodium chloride (NaCl) is an ionic compound. Because of the complete transfer of electrons taking place from a metal, sodium (Na), to a nonmetal, chlorine (Cl), the (Na+ and Cl— ions) are held together by the electrostatic force of attraction that caused the formation of ionic bond in NaCl. How is NaCl ionic bond formed?Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion. Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion.
