Correct Option
Nitroglycerine, also known as glyceryl trinitrate, is a highly potent explosive compound. It is synthesized by the nitration of glycerol using a mixture of nitric and sulfuric acids. This heavy, oily, and colourless liquid is highly sensitive to shock and temperature, making its pure form dangerous to handle. It finds extensive application in industrial blasting, mining, and military ordnance. Its stabilization by Alfred Nobel through absorption in inert materials like diatomaceous earth led to the invention of dynamite, significantly improving its safety and utility.
Incorrect Options
Phosphorus trichloride (A) is primarily used as a reagent in organic synthesis for the chlorination of organic compounds, not as an explosive.
Mercuric oxide (B) is a chemical compound used as a pigment, in batteries, and as a laboratory reagent. It does not possess explosive properties.
Graphite (C) is an allotrope of carbon known for its excellent electrical conductivity, lubricating properties, and high melting point. It is not an explosive material.
