Proofs from Internet sources:

Acetone (systematically named propanone). [1]

Aniline is an organic compound with the formula $\mathrm{C_6H_5NH_2}$. Consisting of a phenyl group attached to an amino group, aniline is the prototypical aromatic amine. [2]

On an industrial scale, cyclohexane is produced by hydrogenation of benzene. [3]

Formaldehyde (systematic name methanal) is a naturally occurring organic compound with the formula $\mathrm{CH_2O}$ (H-CHO). It is the simplest of the aldehydes (R-CHO). [4]

Metal acetates can also be prepared from acetic acid and an appropriate base, as in the popular "baking soda + vinegar" reaction [5]:

$$\mathrm{NaHCO_3} + \mathrm{CH_3COOH} \rightarrow \mathrm{CH_3COONa} + \mathrm{CO_2} + \mathrm{H_2O}$$
