Primary aliphatic
WebSep 30, 2024 · An aliphatic compound is an organic compound containing carbon and hydrogen joined together in straight chains, branched chains, or non-aromatic rings. It is one of two broad classes of hydrocarbons, the other being aromatic compounds. Open-chain compounds that contain no rings are aliphatic, whether they contain single, double, or … WebTherefore, reacting primary amines with nitrous acid leads to a mixture of alcohol, alkenes, and alkyl halides. Primary aromatic amines form stable diazonium salts at zero degrees. …
