Many of the organic solvents commonly used in laboratories have the potential to form explosive peroxide crystals. Diethyl ether and tetrahydrofuran are two of the more common peroxide-forming chemicals used today.

What chemicals can form peroxides?

Common classes of compounds that form peroxides include: Ethers, acetals, and ketals, especially cyclic ethers and those with primary and/or secondary alkyl groups. Aldehydes, including acetaldehyde and benzaldehyde.

Which ether does not form peroxide?

When we examine each reactant's structure, only di(tert-butyl) ether doesn't have an α -proton. So, di(tert-butyl) ether wouldn't be able to be turned into the reactive radical form that generates the peroxide.
