What is a primary (1o) amine?

A primary (1º) amine is an amine that has the following general structural formula. The NH 2 group in a primary amine molecule is called the primary amine group.

What is the difference between 1° and 2° amines?

Hydrogen bonding between 1° and 2° amines is not as strong as those found in alcohols or carboxylic acids. 1° and 2° amines have lower boiling points than alcohols of similar molecular weight. 3° amines, since they do not hydrogen bond to each other, have boiling points similar to hydrocarbons of the same molecular weight.

How do alkyl groups affect the basicity of amines?

Alkyl groups are electron inducing (they seem to act like little electron 'pumps', pushing electrons away from themselves increasing the electron density on the lone pair of the nitrogen. Hence the basicity of amines increases from 1º to 2º to 3º. Aromatic amines have the amine group directly attached to a benzene ring.

What amines react with carbon disulfide and sodium hydroxide?

Most primary and secondary amines react with carbon disulfide and sodium hydroxide to form dithiocarbamates. They are used as ligands for chelating metals. Dithiocarbamates readily react with many metal salts such as copper, ferrous, ferric, cobaltous, and nickel salts and are mostly found as octahedral complexes.
