Cyclopentadiene has an aromatic conjugate base and is more acidic than cyclopropene, reversing (1). The ortho effect makes o-methylbenzoic acid more acidic than benzoic acid, reversing (2). In the intended aqueous comparison, ortho substitution reduces solvation of the protonated amine, so aniline is more basic than o-toluidine: (3). Piperidine is more basic than pyridine, reversing (4). Answer 3.
