Converting Between Fischer, Haworth, and Chair Forms of Carbohydrates.

Check out the topics below for each different class of organic molecules.

There are a total of six relevant steps to follow when naming an organic compound.

A functional group is a group of organic compounds having the same physical and chemical characteristics.

Add Tip Ask Question Comment Download Step 1: Step 1: Detecting and Naming the Parent Chain The parent chain on an organic compound is the longest carbon chain and the chain containing the highest number of substituents highest number of substituents or functional groups.

To detect the longest chain, one needs to just count the number of carbons.

Also, making sure that the chosen chain has the greatest number of substituents and functional groups.

The basis for the names of the longest chain is shown above in figure 2.

The longest chain in the example above wold be a six carbon chain.

As you can see above, the substituents also use the prefix like all other functional groups except they end with the suffix -yl instead of -an.

Figure 4 gives the halogen substituents and their corresponding name.

Using our example in figure 2, the two substituents were ethyl and methyl.

The longest chain will always be the chain with the functional group with the highest priority and the most substituents.

The functional group in our example was an alkane Add Tip Ask Question Comment Download Step 4: Step 4: Naming the Functional Group Depending on the prioritized functional group present, the name or the suffix of the organic compound will be different.

In this case, locate the position of the substituent in your name by the number of that carbon twice.

If you have three, use tri, if you have four, tetra, and so on.

The name of the compound above (example from figure 2) is 4-ethyl-2-methylhexane.
