Document Summary

Organic chemistry: formulae, functional groups and terminology, naming organic compounds, fuels. Draw and interpret the displayed formula of a molecule to show all the atoms and all the bonds. Write and interpret general formulae of compounds in the same homologous series, limited to: (a) alkanes, cnh2n+2 (b) alkenes, cnh2n (c) alcohols, cnh2n+1oh (d) carboxylic acids, cnh2n+1cooh. Identify a functional group as an atom or group of atoms that determine the chemical properties of a homologous series. State that a homologous series is a family of similar compounds with similar chemical properties due to the presence of the same functional group. State that a saturated compound has molecules in which all carbon carbon bonds are single bonds. State that an unsaturated compound has molecules in which one or more carbon carbon bonds are not single bonds. State that a structural formula is an unambiguous description of the way the atoms in a molecule are arranged, including ch2 =ch2, ch3ch2oh, ch3cooch3.

Homologous series

Thealkanes are a homologous series of compounds containing only carbonand hydrogen that have the general formula CnH2n+2.Members of this series include butane (C4H10),3,3-dimethylpentane (C7H16),hexane (C6H14),and heptane (C7H16).

PartA

The boiling points for aset of compounds in a homologous series can be qualitativelypredicted using intermolecular force strengths. Using theircondensed structural formulas, rank the homologous series for a setof alkanes by their boiling point.

c) Only an unsaturated hydrocarbon can engage in an addition reaction.

d) Members of a homologous series differ by a distinct structural unit.

e) Alkanes, alkenes, and alkynes are unsaturated hydrocarbons.

f) Alkyl groups are a class of organic compounds.

g) Isomers have the same molecular formulas but different structural formulas.

h) Cis-trans isomerism appear among alkenes but not alkynes.

i) All aliphatic hydrocarbons are unsaturated.
