Skillbuilders: 4.1-4.8. Practice Problems: 4.38-4.42, 4.45, 4.47, 4.53, 4.55-4.58, 4.60, 4.62-4.65, 4.67-4.69, 4.75, 4.76, 4.81. Starting with Functional Groups These are groups of atoms that have chemical behaviour. • The group reacts • Usually reacts of the rest of the molecule. • e.g., double bonds Hydrocarbon Functional Groups Alternating C–C and C=C bonds Functional Groups with a C–X* Bond * X is an electronegative element Alkyl halide Alcohol Ether Phosphate Amine Thiol Sulfide Disulfide Functional Groups Containing a Carbonyl General Structure of Alkanes Alkanes are compounds with and single bonds. • These can be or . • At times described as or . The structural formula for alkanes with no rings present must be: Recall Condensed Structural Diagrams Remember that condensed structures do not show bonds, only . • e.g., butane:
