SECOND EDITION
The very favorable response to Chemistry Connections encouraged us to prepare
this expanded second edition. We have improved the collection of questions, par-
ticularly to enhance the number of applications in the area anic chemistry.
Furthermore, we have revised anization of questions to assist instructors in
selecting examples to coordinate with the principles and topics covered in their
chemistry classes.
The anization, photographs, and chapter headings will stream-line the
connection with a range of general chemistry textbooks and courses. For the gen-
eral reader, however, our intention is still to demonstrate the wide scope and sig-
nificance of chemistry and the ever-present connection of the discipline to our
daily lives.

Conventions
The answers to many questions include chemical formulas shown mon
drawing notation. For readers unfamiliar with such notation the examples below
should help to interpret the figures. A line represents a chemical bond. The num-
ber of lines between two atoms represents the number of chemical bonds between
the joined atoms. Unless stated otherwise, all lines join two carbon atoms. The
junction of two lines implies the presence of a carbon atom, unless another atom
is shown. Each carbon should have four lines drawn to it. Any missing line should
be interpreted as a bond to a hydrogen atom. For example, a line that terminates
should be viewed as a carbon bonded to three hydrogens and bonded to a fourth
atom shown or implied. In this edition care has been taken to better illustrate the
true three-dimensional structures that molecules represent. To this end, a solid
wedge means the bond ing out of the plane of the page, and a dashed
