Primary and secondary amines have higher boiling points than alkanes of similar moleular weight, but lower boiling points than alcohols of similar molecular mass. Tertiary amines can not provide a H for H bonding, so they have lower boiling points than 1 o or 2 o amines of similar molecular mass. Most low molecular weight amines are soluble in water. Solubility decreases with increasing molar mass. Odor-many low molecular weight amines have odors similar to ammonia.
Many amines have fowl odors.
D. Chirality of Amines and Quaternary Ammonium Salts 1. These isomers cannot be isolated. The R form is converted to the S form and visa versa. Biologically Interesting Amines-many legal and illegal drugs are amines. F. Spectroscopic Analysis 1.
