identify the product formed when a given arylamine is reacted with aqueous bromine. give an appropriate example to illustrate the high reactivity of arylamines in electrophilic aromatic substitution reactions. explain why arylamines cannot be used in Friedel‑Crafts reactions.

2023年11月20日 · use the concept of resonance to explain why arylamines are less basic than their aliphatic counterparts. arrange a given series of arylamines in order of increasing or decreasing basicity. discuss, in terms of inductive and resonance effects, why a given arylamine is more or less basic than aniline.

2024年9月30日 · Primary arylamines react with nitrous acid, HNO 2, to yield stable arenediazonium salts, Ar− N+≡ NX− A r − N + ≡ N X − a process called a diazotization reaction. Alkylamines also react with nitrous acid, but the corresponding alkanediazonium products are so reactive they can’t be isolated.

2015年1月1日 · Some arylamines are mutagenic, carcinogenic or the cause of other kinds of maladies. Some arylamine are considered the major etiological agents of bladder tumors in humans and animals but may also induce other types of cancers in various organs.

Diazonium coupling reactions are typical electrophilic aromatic substitutions in which the positively charged diazonium ion is the electrophile that reacts with the electron-rich ring of a phenol or arylamine.

…class of organic chemicals called arylamines. People who work in the leather, rubber, printing, and textiles industries or with large quantities of paint are often exposed to these chemicals and should exercise caution in their use.

The meaning of ARYLAMINE is an amine (as aniline) containing aryl attached to amino nitrogen.
