Hybridization Channels Available on Pearson+ Problem 1 A molecular model of uric acid is shown in the illustration below. Draw the complete electron-dot structure of uric acid including the lone pairs and multiple bonds, Provide the hybridization of each carbon atom. (gray = C, white = H, red = O, and blue = N) Each of the carbon atoms are sp3 hybridized. Each of the carbon atoms with a double bond is sp2 hybridized and each of the carbon atoms with a single bond are sp3 hybridized. Each of the carbon atoms are sp2 hybridized. Page 1
Hybridization Channels Available on Pearson+ Problem 2 An incomplete Lewis structure of the nucleobase uracil is shown below. Fill in the missing multiple bonds and lone pairs, then determine the hybridization of the highlighted atoms. H / /\/ a C sp3; O: sp3d b. C: sp; O: sp? ¢ C:sp% 0:sp?
Hybridization Channels Available on Pearson+ Problem 3 The structure of furan (C4H40) is shown below. Determine the hybridization of the C atoms and the theoretical value of the C-C=C bond angle. Explain why the actual bond angle is smaller (106 ). ey /°\C _H ' H/ \H Hybridization: sp2 a. Theoretical bond angle: 120 © The actual bond angle is much smaller because the carbon atoms are constrained in a ring. Hybridization: sp3 b. Theoretical bond angle: 109.5 ° The actual bond angle is much smaller because the difference in atomic radius of the atoms. Hybridization: sp c. Theoretical bond angle: 180 © The actual bond angle is much smaller because the carbon atoms are constrained in a ring. Hybridization: sp2 d. Theoretical bond angle: <120 © The actual bond angle is much smaller because the difference in atomic radius of the atoms. Page3

Hybridization Channels Available on Pearson+ Problem 6 The structure of thiophene is shown below. It is drawn in such a way that each corner represents a carbon atom () thiophene and the hydrogens are implicit. Which of the following statement explains why the C-C-C bond angles in benzene are much larger than those in thiophene? a. Thiopene does not exhibit resonance while benzene has resonance structures. b. The carbon atoms adopt smaller angles in a five-membered compared to a six-membered ring. c. The carbon atoms in thiophene have different hybridization from those in benzene.
