Is aniline soluble in water?
Hygroscopic. Moderately soluble in water. Aniline is miscible with alcohol, benzene, chloroform, carbon tetrachloride, acetone, and most organic solvents.
Why aniline is insoluble in water but soluble in HCl?
Explain. Aniline does not undergo hydrogen bonding because of the presence of the benzene which is highly hydrophobic. therefore aniline is insoluble in water. In the HCl the amine group becomes protonated (-NH3+) and the ionic hence soluble in HCl.
Is aniline soluble in water or ether?
Aniline (17), an amine, is soluble in diethyl ether but not water; however, aniline is extracted from diethyl ether with aqueous hydrochloric acid.
What is the solubility of aniline?

Why aniline is basic in nature?
The lone pair of electrons on nitrogen atom in aniline makes it base. Aniline reacts with mineral acids to form salt.
Why is ethylamine soluble in water whereas aniline is not?
Ethylamine when added to water forms intermolecular H−bonds with water. Hence, it is soluble in water. But aniline does not undergo H−bonding with water to a very large extent due to the presence of a large hydrophobic −C6H5 group.
Why aniline are not soluble in water?
Aniline is insoluble in water because of the large hydrocarbon part that retards the formation of an H-bond. So it is insoluble in water. Anilines are the organic compounds in the class of group coming in organic chemistry which are also called aminobenzene or phenylamine.
Is aniline soluble or insoluble in HCl?
Aniline does not undergo hydrogen bonding because of the presence of the benzene which is highly hydrophobic. therefore aniline is insoluble in water. In the HCl the amine group becomes protonated (-NH3+) and the ionic hence soluble in HCl.
How do you make aniline?
Aniline is prepared commercially by the catalytic hydrogenation of nitrobenzene or by the action of ammonia on chlorobenzene. The reduction of nitrobenzene can also be carried out with iron borings in aqueous acid. A primary aromatic amine, aniline is a weak base and forms salts with mineral acids.
Where is aniline used?
Aniline is a representative compound of N-containing aromatic compounds and is mainly used as a chemical intermediate in the production of polymers, pesticides, pharmaceuticals, and dyes [110].
Which is more basic aniline or N Methylaniline?
Aniline is an aromatic amine. The basicity of the aromatic amine is depending upon the availability of the lone pair. In case of aniline due to conjugation the lone pair density is less than that of methylamine. Due to this reason, aniline is less basic than methylamine.
Which is more soluble ethylamine or aniline?
As a result, aniline is less basic than methylamine. Thus, pKb of aniline is more than that of methylamine. (ii) Ethylamine when added to water forms intermolecular H-bonds with water. Hence, it is soluble in water.
