Chemistry 14C Fall 2006 Midterm Exam 1 Page 1 Diazomethane (CH 2 N 2 ) is a toxic, unstable, and explosive gas. In the laboratory, diazomethane can be used for chemical transformation shown below. Questions 1 – 6 refer to diazomethane and its reaction with molecule A . OH O CH 2 N 2 OCH 3 O + OH O A B C 1. (10) In the boxes draw two additional resonance contributors for diazomethane. Less significant resonance contributors will receive less credit. Include formal charges and lone pairs for all contributors. Write “most significant” below your most significant contributors. C N N H H 2. (3) In the box to the right draw the resonance hybrid of diazomethane. Include all lone pairs. 3. (2) Circle the hybridization of these atoms in diazomethane. (a) The carbon atom is. .. sp 3 sp 2 sp p z not hybridized (b) The nitrogen atom not bonded to carbon is. .. sp 3 sp 2 sp p z not hybridized 4. (4) List all of the functional groups in molecules A , B , and C . 5. (2) The best description for the relative position of all of the carbon atoms of molecule A is (circle one): (a) All lie in the same plane. (c) Only six lie in the same plane.
