Below there are two nitrogen containing molecules. the molecule on the left is called an amine, and the molecule on the right is an amide (we will learn more about what these names mean soon). a. add in missing lone pairs to both molecules. b. one of these structures has a resonance contributor. identify the structure with resonance and provide the following: structure of resonance contributor, resonance hybrid structure. c. for each nitrogen atom determine the hybridization and provide the orbital function of all orbitals present on nitrogen. what is the geometry of each nitrogen atom? d. draw an orbital picture to show the location of the lone pairs on nitrogen atoms.

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
