Vedclass · Answer

(D) The solubility of amines in water depends on their ability to form hydrogen bonds with water molecules.$CH_3NH_2$ and $(CH_3)_2NH$ are primary and secondary amines,respectively,which can form hydrogen bonds with water.$C_6H_5NH_2$ (aniline) is less soluble due to the large hydrophobic phenyl group,but it still has an $-NH_2$ group capable of hydrogen bonding.$(CH_3)_3N$ is a tertiary amine and lacks a hydrogen atom attached to the nitrogen atom,meaning it cannot act as a hydrogen bond donor to water molecules.Therefore,$(CH_3)_3N$ is the least soluble in water among the given options.
