4. (3 pt) Rank the below in order of decreasing basicity (most basic first). NH2 NO2 A. i>ii > iii B. iiiiii C. ii >i > iii D. i>iii > ii VH 5. (3 pt) Which of the following can occur? Note: you may have to search for reductions of azides, imines and nitro groups. i RN Hz RNH2 Metal catalyst ii R NH H2 RNH2 Metal catalyst NO2 NH2 H2 Metal catalyst A. ii and iii B. iii C. i D. all of them

Answer 1

Correct structure for XINHEL (R)-N-ethyl-3-methyl cyclopent-2-ene l-amine munet Anticlockwise - S But lower priority group is above the Plane, so Configuration is R. ONK 6 4 Tout 4 28 so 24 Correct option is D. (2R,5R)-5-(3-methoxyphenyl)-N-methyl octanę-2-amine. ome Ph-NH - Ph. I that HONH, is more basic Ans is. (B). more resonating Structure possible. 4 Decreasing basicity Order Correct option is (C). i>is iri' In (ii). elections of N are freely available. In ļ electron involve in resonance. i electron involvement in resonance is mach more due to the presence of No group. (Election with doowing group) ③ Correct ans. is A. D.
