- An carbon-to-oxygen single bond (i.e. C-O) has a bond energy of 358 kJ/mol and an carbon-to-oxygen double bond (i.e. C=O) has a bond energy of 749 kJ/mol. Estimate the value of the carbon-to-oxygen bond energy in the carbonate anion, CO32— . Hint: draw the Lewis structure of CO32— , consider resonance and determine which type of bonds it has. Because of the resonance, the bond between C and O will be somewhere in between the single and double bond. Group of answer choices 1107 kJ/mol 358 kJ/mol 488 kJ/mol 928 kJ/mol 1465 kJ/mol 618 kJ/mol 749 kJ/mol 554 kJ/molWhich of the following bonds are polar: (a) P—O; (b) S—F; (c) Br—Br; (d) O—Cl? Which is the more electronegative atom in each polar bond?There are two main types of covalent bond breakage. In ho-molytic breakage , each atom in the bond gets one of the shared electrons. In some cases, the electronega-tivity of adjacent atoms affects the bond energy. In heterolytic breakage, one atom gets both electrons and the other gets none;thus, a cation and an anion form. (a) Why is the C−C bond in H₃C−CF₃(423 kJ/mol) strongerthan that in H₃C−CH₃(376 kJ/mol)?(b) Use bond energy and any other data to calculate the heat ofreaction for the heterolytic cleavage of O₂.
- Like several other bonds, carbon-oxygen bonds havelengths and strengths that depend on the bond order. Draw Lewis structures for the following species, and arrange them in order of increasing carbon-oxygen bond length and then by increasing carbon-oxygen bond strength: (a) CO; (b) CO₃²⁻; (c) H₂CO;(d) CH₄O; (e) HCO₃(H attached to O).Write a Lewis structure for the amide ion, NH2─, and assign formal charges to each atom.Perchlorates are powerful oxidizing agents used in fire-works, flares, and the booster rockets of space shuttles. Lewisstructures for the perchlorate ion (ClO₄⁻) can be drawn with allsingle bonds or with one, two, or three double bonds. Draw eachof these possible resonance forms, use formal charges to deter-mine the most important, and calculate its average bond order.
- The carbonate anion, CO32- , is a resonance hybrid. Draw all of the important resonance structures for this molecule. If an atom has a nonzero formal charge, be sure the formal charge is shown clearly in the structure. Use the resonance structures to calculate the average formal charge on each O atom (which are all equivalent in the "true" structure). [Note: all of the important contributing resonance structures have octets around each atom that desires an octet.]Draw the Lewis structure of HClO₃ (with minimized formal charges) and then choose the appropriate pair of molecular geometries of the two central atoms. Your answer choice is independent of the orientation of your drawn structure.Assign formal charges to each atom in the interhalogen ion ICl4−.
- Draw the resonance forms that fit the octet rule for the metaphosphate ion, PO 3 – . (a) How many sigma bonds are there? How many pi bonds? (b) What is the phosphorus-oxygen bond order? (c) Arrange the following species in order of decreasing P-O bond strength (strongest first, weakest last). PO 4 3– , PO 2 – , PO + , PO 3What is the formal charge on the chlorine (Cl) atom in PCl₆⁻?Consider peroxynitrite (chemical formula: ONOO−), a structural isomer of the nitrate anion. It is generated in the cell when nitric oxide (NO) reacts with the superoxide radical anion (O2-.). Peroxynitrite is a potent oxidant and nitrating agent and can lead to DNA and protein damage (this is the complete question) Draw the correct Lewis structure for peroxynitrite and indicate approximate bond angles. Tell how many molecular degrees of freedom of motion are present in peroxynitrite and what motions they correspond to.
