Document Summary

R o h: a(cid:374) (cid:862)oh(cid:863) a hydroxyl, the r group (cid:373)ust not start with a carbon that is double bonded to an oxygen. The r represents the rest of the molecule. In organic chemistry we often write out only the part(s) we are directly concerned with. simple alcohols: methanol - ch3oh ethanol - ch3ch2oh. Phenols are special arrangements with a hydroxyl on a benzene ring. In the iupac name, we will look for: Naming alcohols: name longest chain containing oh group-change ending to ol (or phenol), number starting at oh end, name and number other substituents, name a cyclic alcohol as a cycloalkanol. For polyhydroxy alcohols, retain (cid:862)a(cid:374)e(cid:863) suffi(cid:454) a(cid:374)d add (cid:862)diol(cid:863), (cid:862)triol(cid:863), etc. Common nomenclature is regularly used for these alcohols. Toxic. common nomenclature is regularly used for these alcohols. By product of triglyceride hydrolysis. classifying alcohols by number of carbon groups: attached to carbon bonded to the hydroxyl.
