2 3 The Most Sophisticated Representation of Molecules – A Line Drawing C-H bonds are not shown. C has 4 bonds. All other bonds are shown as lines: single bonds = 1 line, double bonds = 2 lines, triple bonds = 3 lines. At the end of each bond is an atom. Carbon atoms are not labeled, other atoms are labeled with their elemental symbols. Bonds to hydrogen and H labels are shown only when they are not attached to a carbon atom. 4 What’s on the exam? See Success Criteria Foundations of Chemistry Activities Gilbert et al textbook (in Bb/Course Documents) Also at least one “Got It!” from 130 SRPC.
