CHM 2047 Homework 5 This assignment is due Friday, Sept. 30, in class. 1. Kotz, Ch. 11, Problem 50. 2. Kotz, Ch. 11, Problem 80. 3. Kotz, Ch. 11, Problem 82. 4. Kotz, Ch. 11, Problem 84. 5. Kotz, Ch. 11, Problem 88. 6. In class we showed that the 2 s and 2 p z orbitals on the oxygen atom in H 2 O have A 1 symmetry, while the 2 p x orbital has B 1 symmetry, and the 2 p y orbital has B 2 symmetry. Determine the symmetry of the 5 3 d orbitals on the oxygen atom. Explain your reasoning! 7. Write a general equation (using R to represent a general alkyl group) for the formation of an ester by the condensation of a tertiary alcohol with a carboxylic acid.

Unformatted text preview: 8. Which will be the stronger acid: propene (CH 2 =CHCH 2 ) or propane (C 3 H 8 )? Explain, using resonance Lewis structures. 9. A compound C 3 H 6 O has a hydroxyl group but no double bonds. Write a structural formula consistent with this information. 10. When an ester forms from an alcohol and a carboxylic acid, an oxygen atom links the two parts of each ester molecules. This atom could have come originally from the alcohol, from the carboxylic acid, or randomly from either. Propose an experiment using isotopes to determine which is the case....
