Why aromatic diazo compounds are stable but aliphatic diazo compounds are not stable?

Why aromatic diazo compounds are stable but aliphatic diazo compounds are not stable?

Aromatic diazonium salts are more stable than aliphatic diazonium salts. Aromatic diazonium salts are more stable than aliphatic diazonium salts. The stability of aromatic diazonium salts is due to resonance which is absent in aliphatic diazonium salts.

Which is the most stable diazonium salt?

Complete answer: Among the given diazonium salts, benzene diazonium halide ${C_6}{H_5}{N_2}^ + {X^ – }$ is most stable due to conjugation of the N,N triple bond with benzene ring.

Why do primary aliphatic amines form highly unstable alkyl diazonium salts?

Primary aliphatic amines form a highly unstable alkyl diazonium salts. Primary aromatic amines form arene diazonium salts which are stable for a short time in solution at low temperature (273— 278 K). The stability of diazonium ions of aromatic amines is explained on the basis of resonance.

Which is more stable aromatic or aliphatic diazonium salts?

If we look at aromatic diazonium salts or their ions they will undergo resonance which causes the delocalisation of positive charge around the benzene ring. Hence, aromatic diazonium salts have better stability than aliphatic diazonium salts.

Why Arene diazonium salts are highly reactive?

Arenediazonium salts are useful intermediates, and they easily lose nitrogen react with a variety of nucleophiles, as shown in the diagram above. Since nitrogen is very stable, and is lost as a gas, this provides a powerful driving force for these reactions to occur.

How do you determine the stability of diazonium salt?

Due to resonance there is a dispersal of positive charge on the benzene ring. This resonance accounts for the stability of the diazonium ion. Hence, diazonium salts of aromatic amines are more stable than those of aliphatic amines. Therefore, the correct answer is option B.

Why diazonium salts of aromatic amines are more stable than those of aliphatic amines?

Due to resonance there is a dispersal of positive charge on the benzene ring. This resonance accounts for the stability of the diazonium ion. Hence, diazonium salts of aromatic amines are more stable than those of aliphatic amines.

Why are aliphatic amines stronger bases than aromatic amines?

Due to the −R effect of the benzene ring, the electrons on the N- atom are less available in case of aromatic amines. Therefore, the electrons on the N-atom in aromatic amines cannot be donated easily. This explains why aliphatic amines are stronger bases than aromatic amines.

Why is aromatic more stable than aliphatic?

Dispersion of positive charge over the benzene ring caused by resonance. Due to resonance there is a dispersal of positive charge on the benzene ring. This resonance accounts for the stability of the diazonium ion. Hence, diazonium salts of aromatic amines are more stable than those of aliphatic amines.

Why are aromatic compounds more stable than aliphatic?

Aromatic compounds have all electron paired whereas anti-aromatic(aliphatic) compounds have unpaired electrons which makes them compounds unstable. Aromatic compounds have high resonance which makes them more stable. Aliphatic compounds are paramagnetic whereas aromatic are diamagnetic.

Which is the best method to introduce fluorine in the aromatic ring?

The present invention concerns itself with a method for introducing fluorine into an aromatic ring structure by using NF 4 BF 4 as a reaction reagent. The introduction is accomplished by an electrophilic substitution reaction in which up to five hydrogen atoms in the aromatic ring can be substituted by fluorine atoms.
