a: O=C(Cn1nnc(-c2cccs2)n1)N1c2ccccc2Sc2ccc(C(F)(F)F)cc21
b: Cc1cccc(OCCCC(=O)Nc2ccc(N3CCOCC3)cc2)c1
c: COc1ccc(CCNC(=O)c2ccc(Cl)c(S(=O)(=O)N3CCCC3)c2)cc1
d: C/C(=N/NS(=O)(=O)c1ccc(Br)cc1)c1ccc(C)o1
e: Cc1ccc2c(c1)c1c(n2CC(O)CN2CCOCC2)CCCC1.Cl
Answer: a. O=C(Cn1nnc(-c2cccs2)n1)N1c2ccccc2Sc2ccc(C(F)(F)F)cc21
