- In the molecular orbital mode l, compare and contrast bonds with bonds. What orbitals form the bonds and what orbitals form the bonds? Assume the z-axis is the internuclear axis.arrow_forwardThe bond length in C2 is 131 pm. Compare this with the bond lengths in C2H2 (120 pm), C2H4 (134 pm), and C2H6 (153 pm). What bond order would you predict for C2 from its bond length? Does this agree with the molecular orbital configuration you would predict for C2?arrow_forwardGive the hybridization of each central atom in the following molecules. (a) cyclohexene (b) phosgene, Cl2CO (c) glycine, H2NC(1)H2C(2)OOH (Note: Numbers in parentheses label each carbon atom.)arrow_forward
- Aspirin, or acetylsalicylic acid, has the formula C9H8O4 and the skeleton structure (a) Complete the Lewis structure and give the number of bonds and bonds in aspirin. (b) What is the hybridization about the CO2H carbon atom (colored blue)? (c) What is the hybridization about the carbon atom in the benzene-like ring that is bonded to an oxygen atom (colored red)? Also, what is the hybridization of the oxygen atom bonded to this carbon atom?arrow_forwardWhat are the relationships among bond order, bond energy, and bond length? Which of these quantities can be measured?arrow_forwardThe structure of amphetamine, a stimulant, is shown below. (Replacing one H atom on the NH2, or amino, group with CH3 gives methamphetamine a particularly dangerous drug commonly known as speed.) (a) What are the hybrid orbitals used by the C atoms of the C6 ring. by the C atoms of the side chain, and by the N atom? (b) Give approximate values for the bond angles A, B, and C. (c) How many bonds and bonds are in the molerule? (d) Is the molecule polar or nonpolar? (e) Amphetamine reacts readily with a proton (H+) in aqueous solution. Where does this proton attach to the molecule? Explain how the electrostatic potential map predicts this site of protonation.arrow_forward
