What is the iupac name for the compound shown

In order to give compounds a name, certain rules must be followed.

In order to name organic compounds you must first memorize a few basic names. These names are listed within the discussion of naming alkanes. In general, the base part of the name reflects the number of carbons in what you have assigned to be the parent chain. The suffix of the name reflects the type s of functional group s present on or within the parent chain. Other groups which are attached to the parent chain are called substituents. Alkanes - saturated hydrocarbons The names of the straight chain saturated hydrocarbons for up to a 12 carbon chain are shown below.

.

The carbon atoms will be numbered from right to left so that the carboxylic acid functional group has the lowest numbered carbon atom. Draw the structure: There is a triple carbon-carbon bond.

Nomenclature , a collection of rules for naming things, is important in science and in many other situations. The simplest of these are binary compounds , those containing only two elements, but we will also consider how to name ionic compounds containing polyatomic ions, and one specific, very important class of compounds known as acids subsequent chapters in this text will focus on these compounds in great detail. We will limit our attention here to inorganic compounds, compounds that are composed principally of elements other than carbon, and will follow the nomenclature guidelines proposed by IUPAC. The rules for organic compounds, in which carbon is the principle element, will be treated in a later chapter on organic chemistry. To name an inorganic compound, we need to consider the answers to several questions.

What is the iupac name for the compound shown

One way of checking whether the name you have given to an alkane is reasonable is to count the number of carbon atoms implied by the chosen name. If you were to check the given structure and find 11 carbon atoms, you would know that you had made a mistake. When naming alkanes, a common error of beginning students is a failure to pick out the longest carbon chain. Remember that every substituent must have a number, and do not forget the prefixes: di, tri, tetra, etc. You must use commas to separate numbers, and hyphens to separate numbers and substituents.

This molecule is therefore propanoic acid. Determine the number of carbon atoms in the longest chain containing the functional group The prefix for the compound is but- so there must be four carbons in the longest chain containing the double bond. Combine this information and add the hydrogen atoms Carbon atoms can have four single bonds. Number the carbon atoms in the carbon chain The carbon atoms will be numbered so that the carbon atom of the aldehyde group has the lowest number possible. The suffix yne tells us this is an alkyne and there is a triple bond between the second and third carbon atoms. Find the longest carbon chain containing the functional group There are six carbon atoms in the longest chain containing the functional group. Use three toothpicks to represent a triple bond. There are three carbons in the longest chain that contains the functional group. There are only single carbon-carbon bonds and no other functional group so the compound is an alkane and the suffix is -ane. The two alkyl groups attached to the oxygen are put in alphabetical order with spaces between the names and they are followed by the word ether.

With the ability to identify functional groups, next we will learn how to give IUPAC names to compounds containing a few functional groups, by following a set of rules. For naming purposes, the functional groups are assigned with priorities Table 2. The order of the groups listed in Table 2.

There are five carbon atoms in the chain without the carbonyl group from the alcohol , therefore this group is pentyl. Give the structural representation for the following:. This compound is an alkyne and will have the suffix -yne. There is one carbon atom in the chain with the carbonyl group from the carboxylic acid , therefore the prefix is methan-. What is the name of the new molecule? Follow the examples. A ketone has the suffix -one. There is a carbonyl group and an oxygen atom attached to two different carbon atoms. The triple bond is between the second and third carbon atoms regardless of how you number the chain yne. Summary of functional groups. The carbon atoms will be numbered so that the carbon atom of the aldehyde group has the lowest number possible.
