Module 4 Core Organic Chemistry (AS Chemistry OCR A) CORRECTLY ANSWERED

What is a Saturated Hydrocarbon correct answers A saturated hydrocarbon is a molecule containing only hydrogen and carbon atoms with single bonds only between the atoms. What is an Unsaturated Hydrocarbon correct answers An unsaturated hydrocarbon is a molecule containing only hydrogen and carbon atoms with one or more carbon-to-carbon multiple bonds What is a Homologous Series correct answers A family of compounds with similar chemical properties whose successive members differ by the addition of a CH2 group e.g. alkane What is a Functional group correct answers The part of an organic molecule that is largely responsible for the molecule's chemical properties. What is Aliphatic correct answers Carbon atoms are joined to each other in an unbranched (straight) or branched chain What is Alicyclic correct answers Carbon atoms are joined to each other in a ring (cyclic) structures What is Aromatic correct answers Some or all of the carbon atoms are found in a benzene ring What is an Alkane correct answers Homologous series of aliphatic hydrocarbons Contains single carbon-to-carbon bonds What is an Alkene correct answers Homologous series of aliphatic hydrocarbons Containing at least one double carbon-to-carbon bond What is an Alkyne correct answers Homologous series of aliphatic hydrocarbons Containing at least one triple carbon-carbon bond What is the Stem of the name when naming organic molecules? correct answers Indicates the number of carbon atoms in the longest continuous chain in the molecule What is the Prefix of the name when naming organic molecules? correct answers Added before the stem, often to indicate the presence of side chains or functional groups What is the Suffix of the name when naming organic molecules? correct answers Added after the name to indicate functional groups Naming aliphatic alkanes correct answers 1. All alkanes have the suffix -ane 2. Identify the longest continuous chain of carbon atoms and name it 3. Identify the side chains attached to the parent chain. They are known as alkyl groups. 4. Add numbers to any alkyl groups to show their position on the parent chain
