Formaldehyde is a common carbonyl compound found in e-cigarettes due to its formation during the heating process of the e-liquids. In the context of e-cigarettes, when the glycerol and propylene glycol used in many vape liquids are heated, they can undergo thermal decomposition, resulting in the generation of various carbonyl compounds, including formaldehyde.

Formaldehyde is significant because it is a known irritant and has been associated with various health risks, particularly when inhaled. Its presence in e-cigarettes draws attention to the potential risks of using these devices, especially considering that users may not be aware of the harmful compounds generated during vaping.

The other substances mentioned do not fit the criteria of being common carbonyl compounds found in e-cigarettes. Ozone can be produced by electronic devices but is not specifically a component of e-cigarette vapor. Hydrogen sulfide is associated with foul odors and is not typically present in vape products. Acetic acid, while it may be found in various contexts, does not represent the common carbonyl compounds typically discussed in relation to e-cigarettes.
