Which liquid is listed as an explosive material?

• A. Acetone
• B. Glycerin
• C. Methanol
• D. Water

Answer: (A)

A key idea here is how some liquids can become hazardous over time due to chemical changes that make them explosive. Acetone is known to form unstable organic peroxides when it sits exposed to air and light, especially as it ages. These peroxides can be highly sensitive to heat, shock, or friction and can detonate, so acetone is listed as an explosive material in safety contexts. The other liquids don’t carry that same explosive-forming hazard in normal lab classifications: methanol is primarily a flammable solvent, water is non-hazardous in this respect, and glycerin by itself isn’t typically listed as explosive (though it can be involved in explosive processes if chemically altered). So acetone is identified as the explosive-listed liquid because of the peroxide-formation risk it presents.
