Bcoz alipatic amines require very low temperature like about -25 degrees celsius...which is difficult to maintain.....thats y its not posible to form diazonium salt with aliphatic amines...where as for aromatic amines its posible as temperature range is 0 - 5 degres..
A butylamine is any of four isomeric aliphatic amines derived from butane.
Aliphatic amines do not typically give coupling reactions due to their limited aromatic character, which is necessary for coupling reactions to occur effectively. Aromatic amines are more likely to undergo coupling reactions because they possess a delocalized pi system that stabilizes the intermediates formed during the coupling process.
Diazotization involves the conversion of an aromatic primary amine compound to a diazonium salt by reaction with nitrous acid at low temperatures. This reaction is important in the synthesis of azo dyes, pharmaceuticals, and other organic compounds. The diazonium salt formed is a versatile intermediate that can undergo various substitution reactions to introduce different functional groups onto the aromatic ring.
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
One Nitrogen atom = one -NH2. H3C-CH2-CH2-NH2. 1-amino-propane.
Aliphatic amines are stronger bases than aromatic amines because the lone pair on the nitrogen atom in aliphatic amines is more available for donation due to the absence of resonance effects that stabilize the lone pair in aromatic amines. This makes aliphatic amines more likely to accept protons and act as bases.
A butylamine is any of four isomeric aliphatic amines derived from butane.
Aliphatic amines are organic compounds containing nitrogen atoms bonded to saturated carbon atoms, typically forming a chain-like structure. These compounds have a wide range of applications in various industries, including pharmaceuticals, agriculture, and materials science. Examples of aliphatic amines include primary, secondary, and tertiary amines.

There are three possible primary amines for the formula C4H11N: 1-aminobutane, 2-aminobutane, and 2-methyl-1-aminopropane.
Diazotization is a chemical process that involves conversion of primary aromatic amines into diazonium salts by reaction with nitrous acid (HNO2). This reaction is commonly used in organic synthesis to introduce a diazo group (-N2+) onto an aromatic ring, which can then undergo various substitution reactions.
When a solution of ArN-NO is acidified, it will result in the generation of the corresponding diazonium salt ArN2+. This reaction is known as diazotization and is a common method for converting aromatic primary amines to diazonium salts.

In aqueous medium, formation of NO+ ion takes place. Addition of KBr, increases the electrophilicity of this nitonium ion. This is due to higher electronegativity of (Br), as it pulls the electron cloud towards itself. Hence, the NO+ reacts faster with the amine.
There is no such thing as Aliphatic petroleum distillates. Petroleum distillates is the term used to refer to aliphatic hydrocarbons. These are typically solvents.
