amine + hcl mechanism

How do aliphatic amines react with nitrous acid?
Primary aliphatic amines with nitrous acid give very unstable diazonium salts which spontaneously decompose by losing N 2 to form a carbenium ion. The carbenium ion goes on to produce a mixture of alkenes, alkanols or alkyl halides, with alkanols as the major product.
How do amines form salts?
Amine - Reactions, Synthesis, Properties: Amines characteristically form salts with acids; a hydrogen ion, H+, adds to the nitrogen. With the strong mineral acids (e.g., H2SO4, HNO3, and HCl), the reaction is vigorous. Salt formation is instantly reversed by strong bases such as NaOH.
How do amines react with acid chlorides?
Ammonia, 1 o amines, and 2 o amines react rapidly with acid chlorides or acid anhydrides to form 1 o, 2 o, and 3 o amides respectively (Sections 21-4 and 21.5). These reactions typically take place rapidly at room temperature and provide high reaction yields.
What happens if amine salt is heated to 200°C?
Upon heating to 200°C, the primary and secondary amine salts dehydrate to form the corresponding amides. Amines R 3 N react with strong acids such as hydroiodic acid (HI), hydrobromic acid (HBr) and hydrochloric acid (HCl) to give ammonium salts R 3 NH +. Nitrous acid with the chemical formula HNO 2 is unstable.
