a Cc1cc(C=O)c(C)n1-c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
b O=C(COC(=O)c1ccc[nH]c1=O)NC1CCCCCCC1
c CCc1cccc(C)c1NC(=O)CN(C)Cc1ccccc1F.O=C(O)C(=O)O
d O=C(NCC1CC1)C1(C(F)(F)F)CC(CCc2ccccc2)CCCO1
e O=c1[nH]c(CSc2ncc(C(F)(F)F)cc2Cl)nc2cc(C(F)(F)F)ccc12
Answer: a. Cc1cc(C=O)c(C)n1-c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
