What is the major organic product obtained from the following reaction? A) 1 B) 2 C) 3 D) 4 8. What is the major organic product obtained from the following reaction? NH2 1. L?AH, 2 H2O A) 1 B) 2 C) 3 4 D) 4 8I Page

Answer 1

33) B claisen condensation

34)B 1 and 3 Secondary amine is the form R2NH ie two different or same R groups attached to the nitrogen of the amine

35) D 1=amide, 2=amine 3=hydrazone

amide is R(C=O)NH2 amine is R-NH2 and hydrazone is R2C=NHR

36) A (E)-1-amino-4-hexene (E is because he priority groups are on opposite sides of the double bond). Amino has higher priority than alkene so numbering starts from amino group
