Why diazonium salts of aromatic amines are more stable than those of aliphatic amines?
the intermediate positively charged nitrogen is being supplied by large electron clouds coming from both sides, i.e., the intermediary triple bonds with the other N that is attached to a conjugate base (that's why it is a diazonium salt) and the pi electron cloud from the benzene ring.... this makes the aromatic diazonium salt much more stable
on the other hand, the intermediate positively charged nitrogen is much less stable due to a weak van der waals and london forces coming from the aliphatic alkyl chain although the intermediary triple bonds of another nitrogen is near-by.
thus, it is the large pi electron cloud of the aromatic ring which stabilies the positively charged nitrogen of the diazonium salt
What else can I help you with?
Which is stronger acid aromatic or aliphatic?
Aromatic acids are generally stronger than aliphatic acids due to the resonance stabilization provided by the delocalization of electrons in the aromatic ring. This makes the aromatic acids more stable when releasing a proton, resulting in a stronger acid.
Why aromatic diazo compounds are more stable than aliphatic diazo compounds?
aromatic diazo compounds are stabilize by resonance where as in alifati it is not found
Why aromatic compound undergoes electrophilic substitution?
in aromatic amines due to the presence of of the amine group, the conjugation of the benzene ring proceeds through making the ring more stable.
What is the difference between aromatic and aliphatic compounds?
Aliphatic compounds could be straight chain structures [Acyclic] like alkanes or cyclic structures, like cycloalkanes. Aliphatic compounds are hydrocarbon chains - strings of carbon atoms connected to each other with hydrogen atoms hanging off the sides of the chain. one exception for the definition of aliphatic side chain is Proline which also has aliphatic side chain but the its side chain is bonded to both carbon and nitrogen. Aromatic compounds have benzene ring (older notion). Aromatic compounds are those which follow Huckel's rule. (4n + 2pi) rule. They have the general formula: CnH2n-6 [where n is equal to or greater than 6] Aromatic compounds are rings - so take the chain and connect the two ends together to form a continuous loop.
What are characteristics of aromatic hydrocarbons?
Principal characteristics of aromatic hydrocarbons are:- the contain benzenic rings- frequently they have an agreeable odor- they burn with soot; this is a disadvantage- the ratio carbon/hydrogen is great
Which is stronger acid aromatic or aliphatic?
Aromatic acids are generally stronger than aliphatic acids due to the resonance stabilization provided by the delocalization of electrons in the aromatic ring. This makes the aromatic acids more stable when releasing a proton, resulting in a stronger acid.
Why aromatic diazo compounds are more stable than aliphatic diazo compounds?

Why aryl diazonium salt are more stable then alkyl diazonium salt?
Aryl diazonium salts are more stable because the aromatic ring stabilizes the positive charge on the nitrogen atom through resonance, spreading the charge over a larger area. In contrast, alkyl diazonium salts lack this resonance stabilization, making them less stable.
What is the difference of aliphatic and aromatic hydrocarbons?
Aliphatic hydrocarbons have straight or branched carbon chains, while aromatic hydrocarbons contain a benzene ring or other aromatic rings in their structure. Aliphatic hydrocarbons are typically less stable and more reactive than aromatic hydrocarbons due to differences in bond types and energy. Aromatic hydrocarbons exhibit unique properties such as resonance stabilization and are often used as precursors for various organic compounds.
Why aromatic compound undergoes electrophilic substitution?

Does benzoic acid have an odor?
Acetic acid is an aliphatic (fatty) acid and a liquid while benzoic acid is an aromatic acid which exists in solid state.
Are non aromatic compounds stable or unstable?
Non-aromatic compounds can be stable or unstable, as stability is determined by factors such as bond strength, molecular structure, and energy content. Non-aromatic compounds can exhibit varying degrees of stability, depending on their specific chemical composition and environment.
What is a characteristic of a aromatic hydrocarbons?
Alternating single and double bonds
Why phenol is stronger acid than ethanol?
Phenol is a stronger acid than ethanol because the phenoxide ion formed after losing a proton is stabilized by resonance, making it more stable. In contrast, ethanol forms a less stable ethoxide ion due to the lack of resonance stabilization. This difference in stability influences the ease with which the acids donate a proton.
Why is tertiary amine more stable than ethanol?
Tertiary amines have alkyl groups around the central atom (nitrogen) while ethanol has hydrogen atoms and one hydroxyl group around the carbon atoms. As a result, ethanol is more prone to attack by other groups while in tertiary amines, stearic hindrance doesn't allow attack of incoming groups. So, tertiary amines are more stable than ethanol.
