Which of the following is an organic peroxide?

Methyl ethyl ketone peroxide is classified as an organic peroxide because it contains the peroxide functional group (-O-O-) attached to organic compounds. Organic peroxides are known for their ability to decompose, often releasing oxygen and generating heat, which can pose significant hazards during transportation and storage.

In contrast, ammonium nitrate is an inorganic compound typically used as a fertilizer and can act as an oxidizer but does not have the organic structure necessary for classification as an organic peroxide. Hydrogen peroxide, while it contains the peroxide bond, is not considered an organic peroxide because it is a simple inorganic compound. Charcoal briquettes are solid fuels derived from carbonized organic matter and do not exhibit the characteristics of organic peroxides. Therefore, methyl ethyl ketone peroxide stands out as the only correct answer in this context.
