Document Summary
1. 1 the scope of organic chemistry: an overview. Functional groups: the organic molecules that determine the whole molecules chemical reactivity relative positioning of their component atoms in space. Lack functional groups, are the basic scaffold of organic molecules. Composed of only carbon and hydrogen atoms (cid:523)(cid:494)hydrocarbons(cid:495)(cid:524) Stereoisomerism: shown in compounds with the same connectivity but different.

Substitution reaction: one halogen atom may be replaced by another. Elimination: adjacent atoms can be removed from a molecule to generate a. Reactions are the vocabulary and mechanisms are the grammar of organic chemistry. Reaction intermediates: species formed on the pathway between reactants and the. Opposite charges attract each other (electrons are attracted to protons. Like charges repel each other (electrons spread out in space)
