PS questions 1. (2 pt) Which is the correct structure for (R)-N-ethyl-3-methylcyclopent-2-en-1-amine? A INHEt Et > NHEN VEt | ANH NHA | NHẤt A 2. (2 pt) Which is the correct name for the structure? HN1 A. (4R,7R)-4-(3-methoxyphenyl)-N-methyloctan-7-amine B. (48,7R)-4-(3-methoxyphenyl)-N-methyloctan-7-amine C. (2R,5S)-5-(3-methoxyphenyl)-N-methyloctan-2-amine D. (2R,5R)-5-(3-methoxyphenyl)-N-methyloctan-2-amine OMe 3. (3pt) Why is HONH2 more basic? Note the pka values are for the conjugate acids. HONH2 ZI A. diphenylamine has more resonance structure after protonation B. the Nitrogen electrons on diphenylamine can resonanate into the rings making them less available to bond with H+. C. diphenylamine has less s character in the nitrogen atom D. the N electrons on diphenylamine are aromatic pka = 1 6
