Final answer:
Organic chemicals that are most likely to form peroxides are those that have a carbon-oxygen bond next to a hydrogen atom or a carbon-carbon bond next to two oxygen atoms. Examples include diethyl ether, tetrahydrofuran, and dioxane.
Step-by-step explanation:
Some organic chemicals are hazardous because they have the ability to form peroxides. Peroxides are compounds that contain an oxygen-oxygen single bond (-O-O-).
Organic chemicals that are most likely to form peroxides are those that have a carbon-oxygen bond next to a hydrogen atom or a carbon-carbon bond next to two oxygen atoms. For example, organic solvents like diethyl ether, tetrahydrofuran, and dioxane are known to form peroxides.
