Yes. The ammonium ion has a formula of NH4+ and has a positive charge so it is a cation.
The first two are classified as 1Âº-amines, since only one alkyl group is bonded to the nitrogen; however, the alkyl group is primary in the first example and tertiary in the second. The third and fourth compounds in the row are 2Âº and 3Âº-amines respectively.A nitrogen bonded to four alkyl groups will necessarily be positively charged, and is called a 4Âº-ammonium cation. For example, (CH 3) 4 N (+) Br (â) is tetramethylammonium bromide.he third and fourth compounds in the row are 2Âº and 3Âº-amines respectively.
