Quiz #3 1. Provide the IUPAC name or line angle formula for the following compounds. A. B. CH 3 C H 3 CH 3 CH 3 C H 3 CH 3 CH 3 CH 3 CH 3 Name: 5-sec-butyl-4-isopropy-2,3,7- trimethylnonane Name: bicyclo[4.3.0]nonane 2. A. Identify the major functional group. B. label the potential for the functional group to form H-bond with itself and/or with water Note: The example problem is not necessarily correct Structure Classification Hydrogen Bond Potential C H 3 SH thiol H-bond with itself only N CH 3 C Nitrile H bonding to itself C H 3 C H 3 O CH 3 Ether No H bonding 3. Which of the following does not represent a resonance form of the structure below? C + O CH 3 CH 3 A. B. C. D. O + CH 3 CH 3 CH 3 C + O CH 3 CH 3 O CH 3 All are resonance forms

Unformatted text preview: copy and paste these structures back and forth into ISIS to add arrows. Note: Me = methyl group = CH 3 Nucleophile electrophile Electrophile nucleophile 5. The following reactions represent Bronstead acid-base reactions. For each reaction, label the acid, base, conjugate acid, conjugate base and predict if the reaction will go faster in the forward or reverse direction and briefly explain. C H 3 NH-O C H 3 NH 2 C H 3 NH 2 O C H 3 NH-+ + Base acid conjugate base conjugate acid It would react faster in the forward reaction because the con. acid is more electronegative and will dissociate easier in the solution. C H H H C H H OH Na+ -:N H H C H H H C H H O- +Na N H H H + + Base acid conjugate base conjugate acid It would react faster in the forward reaction because the OH compound is more electronegative and the NH 3 compound is more stable....
