Alcohol IUPAC Naming - Alcohol Alcohol = an -OH group Connected to an aliphatic carbon R-OH Phenol = an -OH group Connected to an aromatic carbon Ar-OH Ether = an oxygen between two carbons R-O-R Common Naming Give alkyl parent chain name Followed by alcohol If 2 -OH groups "diy" at the end Alcohol Physical Properties neutral Polar -OH alcohol end Distinctive odors High melting + boiling point Very water soluble up to 4 carbons Slightly water soluble up to 7 carbons Water Solubility depends on a molecules ability to make hydrogen bonds with water alcohols + ethers can hydrogen bond with water alkanes cannot! H3C-CH2-OH ethanol ethyl alcohol Stronger the intermolecular forces between molecules of the same compound the higher the B.P Alcohols can hydrogen bond with themselves Alkanes + ethers cannot An alcohol molecule is part hydrocarbon + part water
