Five series of N-aryl-4-alkoxybenzamides [RO–C 6H 4–CONH–C 6H 4–X] were prepared where the terminal alkoxy group (RO) possesses a number of carbon atoms ( n) that varies between 8, 10, 12, 14, or 18 carbons, while the other terminal substituent (X) alternatively changes from CH 3O, CH 3, H, Cl, and...
