Nitration is a chemical process that involves the introduction of a nitro group into an organic compound. The word "nitration" is spelled as /naɪ.treɪ.ʃən/, with the stress on the second syllable. The first syllable is pronounced with the diphthong "ai" as in "eye," followed by the sound of the letter "t." The second syllable contains the sounds of "a" and "e," followed by the sound of "sh" and the short "uh" sound. The final syllable is pronounced with the sound of "sh" and the long "un" vowel as in "nation."
Nitration is a chemical process that involves the introduction or insertion of a nitro group (-NO2) into a compound or molecule. It specifically refers to the reaction of an organic compound with nitric acid (HNO3) or its derivatives, resulting in the addition of a nitro group to the compound. The reaction is facilitated by the presence of a strong acid catalyst, such as sulfuric acid (H2SO4), which helps initiate the reaction and stabilize the resulting nitrated product.
During nitration, the highly reactive nitronium ion (NO2+) is formed as an intermediate species through the dissociation of nitric acid. This nitronium ion acts as an electrophile and attacks the electron-rich regions of the organic compound, usually resulting in the substitution of a hydrogen atom with the nitro group. Nitration reactions are typically exothermic and require careful control of reaction conditions, as they can be highly energetic and can even lead to explosion in certain cases.
Nitration is an important process in organic chemistry and is extensively utilized in the manufacturing of a wide range of products, including pharmaceuticals, dyes, explosives, and agrochemicals. The resulting nitrated compounds often exhibit altered chemical and physical properties due to the addition of the nitro group, which can affect their reactivity, solubility, color, and pharmacological activity. Nitration represents a key reaction in the synthesis of various compounds and is crucial in the development of many useful materials and substances.

The word "nitration" is derived from the noun "nitrate", which is in turn derived from the Latin word "nitrum", meaning "saltpeter" or "potassium nitrate". The Latin term comes from the Greek word "nitron", which refers to a mineral salt. Nitration specifically refers to the chemical process of introducing a nitro group (NO2) into a chemical compound through the reaction with a nitric acid.
