There is one carbon atom in the longest chain so the prefix is meth. Remember to store it in an airtight container between uses. Remember, they belong to the homologous series of the alcohols. Combine the elements of the compound's name into a single word in the order of branched group; prefix; name ending according to the functional nomenclarure The compound's name is 2-methylpropane.The hexyl tells us that there are six carbon atoms in the chain without the carbonyl group from the alcohol. In this case you can number from either side. If the same group appears more than once on the same carbon atom, the number of that carbon atom is repeated as many times as the group appears. Combine the elements of the name into a single word in the following order: branched groups; prefix; name ending according to the functional group and its position iupwc the longest carbon chain The name bedt this compound is butene or 2-butene!
There are no branched groups, so nomencpature molecule is ethane. Note that butanone can only be butanone. Combine the elements of the compound's name into a single word in the order of branched group; prefix; name ending according to the functional group The compound's name is 2-methylpropane. The first double bond occurs between carbons 1 and 2.
The compound has the nomenvlature -al! The first one is attached to the second carbon atom and the second methyl group is attached to the third carbon atom. There are no branched groups?
The double bond occurs between carbons 2 and 3. Boook placing the hydroxyl group at different positions within the molecule. There are five carbon atoms in the chain without the carbonyl group from the alcoholtherefore this group is pentyl. There are only single bonds in this compound and no other functional groups, therefore it is an alkane and the suffix is -ane.
As noted in previously, the number of isomers increases rapidly as the number of carbon atoms increases.

Worked example 1: Naming the alkanes
In order to give compounds a name, certain rules must be followed. This is to give consistency to the names. It also enables every compound to have a unique name, which is not possible with the common names used for example in industry. We will first look at some of the steps that need to be followed when naming a compound, and then try to apply these rules to some specific examples. A good general rule to follow is to start at the end the suffix and work backwards from right to left in the name.
Education in Chemistry. The prefix for this compound will be butan. You need to number the carbon atoms so that the halogen atoms are on the carbon atoms with the lowest numbers. The functional group is a triple bond, so the longest chain must contain the triple bond?
A second printing of the third edition was released in ; this printing made several minor revisions to the text. The compound is a hydrocarbon nomenclture single bonds between the carbon atoms. After functional groups, the branched groups should have the lowest numbers possible. There are two branched groups attached to the fourth carbon atom remember to count from the carboxylic acid functional group.
