The chain is numbered to give the halogen the lowest possible number. The C-X bond of an alkyl halide becomes longer and weaker as the size of the halogen increases.X. R-O-R symmetric ether R-O-R’ nonsymmetrical ethera. Ethyl methyl ether, diethyl ether, tert-butyl isobutyl etherb. CH3Omethoxy, CH3CH2Oethoxy, isopropoxy, 2-methoxybutane, 1-butoxy-2,3-dimethylpentaneXI. R-CH2-OH primary alcohol, secondary alcohol, tertiary alcohol. Common alcohols: ethyl alcohol, propyl alcohol, isopropyl alcohol, isobutyl alcohol. CH3OH Methanol andCH3CH2OH ethanol are common names of some alcohols. In these compounds, the OH is These notes represent a detailed interpretation of the professor’s lecture.

Alcohols are named by replacing the “e” at the end of compounds with “nol”. The number can precede the name of the parent hydrocarbon (ex. 3-methyl-1-hexanol) or it can precede the suffix itself (ex. 3-methylhexan-1-nol). Remember that the substituent is always the prefix and the functional group is always the suffix. [substituent][parent hydrocarbon][functional group]When there is both a substituent and a functional group, functional groups always get the lowest number possible.Ex 3-bromo-1-propanol, 4,4-dimethylpent-2-nolXII. Systematic Names of Diols are similar to those of alcoholsEx. 2,4-hexanediol or hexane-2,4-diolXIII. Amines have three groups, primary, secondary, and tertiary.Ex. NH3ammoniaa. The suffix “amine” denotes the amine functional group. A substituent on the nitrogen is indicated by “N”.Ex. 1-butanamine, N-ethyl-N-methylpropan-1-amine,
