Document Summary
Alcohols and alkyl halides: introduction to reaction mechanisms. Functional group: an atom or a group of atoms in a molecule responsible for its reactivity under a given set of conditions. Mechanisms: the sequence of steps that describes how a chemical reaction occurs; a description of the intermediates and transition states that are involved during the transformation of reactants to products. Alkyl halide: compound of the type rx, in which x is a halogen substituent (f,cl,br,i) Can be named in 2 different ways: functional class nomenclature substitutive nomenclature. Functional class nomenclature: compounds are named according to functional group families. The last word in the name identifies the functional group. The first word designates the alkyl group that bears the functional group. Substitutive nomenclature: substance is identified by a name eding in a suffix characteristic of the type of compound. Treats halogen as halo (fluoro-, chloro-, bromo-, iodo) 4. 3 iupac nomenclature of alcohols (-oh) then adding alcohol as a separate word.
