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
Aromatic diazonium salts are resonance stabilized and hence are more stable than the highly unstable aliphatic diazonium salts(which release N2 and ROH).
However the aromatic diazonium salts are very stable for a short period of time.
because of dispersal of +ve charge on the benzene ring due to resonance.
aromatic diazo compounds are stabilize by resonance where as in alifati it is not found
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.
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.
Such compound is only Ninhydrin, an aromatic diketo diol.
Aromatic rings tend to be more stable than non-aromatic rings, if that's what you're asking. I'm not quite sure what the question means.

Acetic acid is an aliphatic (fatty) acid and a liquid while benzoic acid is an aromatic acid which exists in solid state.

The reason is that the aryl group is able to stabalize the diazonium salt through resonance, while the alkyl group may not be resonance stabalized.
Because it is aromatic
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
Such compound is only Ninhydrin, an aromatic diketo diol.
because of conjugation with the aromatic ring
Aromatic compounds are resonance stabilized. Hence if a compound is aromatic it is more stable. The main thing to note here is that AROMATICITY GIVES STABILITY TO A COMPOUND. Therefore cyclopropene is an aromatic compound and hence is more stable than propene.
C6H6, the formula for benzene, which is the simplest stable and electrically neutral aromatic compound.
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.
