How To Name A Functional Group

The principal functional group is O and the suffix one will end the name of the parent hydrocarbon because the O is on a non-terminal carbon atom. For alkyl halides and alcohols the classification is based on the number of carbons attached to the carbon directly attached to the halide or OH group.

Number the parent chain starting from the highest priority group.

How to name a functional group. Drop the e ending and add ol the ending for alcohol. Identify the functional groups in the molecule circle them name the type of compound and name the functional group if they have it. The ending of the name as a suffix tells the type of compound or functional group present.

A 3 carbon alcohol is named as. How to name each group. The root name tells the number of carbons in the longest continuous chain.

Example upper left - most organic names. Determine the group with a higher priority using the functional group priority table below. Substituent positions are shown with Greek letters.

For the remaining functional groups alkyl halides alcohols amines the functional group can be classified as 1 2 3 or 4. Three carbon root name propane. CH 3 CH 2 CH 2-OH propanol.

Recall that if more than 1 functional group appears on a molecule the higher priority group is named in the suffix and the lower priority group is demoted to substituent status and named in the prefix. I did need to dig. A functional group is a part of an organic molecule.

The name is derived as follows. The O functional group is more senior than the OH functional group. For the common name of aldehydes start with the common parent chain name and add the suffix -aldehyde.

Write name as a single word use hyphens to separate numbers and letters use commas to separate numbers. The aldehyde funtional group is given the 1 numbering location and this number is not included in the name. Identify the functional groups in the molecule circle them name the type of compound and name the functional group if they have it.

Generally functional groups dicate how the molecule reacts with different chemical s too. Name and number the substituents if t o gro ps on same C gi e same n mberif two groups on same C give same number if same group appears more than once use di tri. Treat the ketone as a substituent and remember those are added with a prefix oxo.

The R group is a convenient way to abbreviate the structures of large biological molecules especially when we are interested in something that is occurring specifically at one location on the molecule. Replace -ane ending with -yl for substituents 4. The -e is removed from the end and is replaced with -al.

Aldehydes take their name from their parent alkane chains. So this molecule is named as an alkan one Consider the molecule shown below. If we just want to refer in general to a functional group without drawing a specific molecule for example we can use R groups to focus attention on the group of interest.

The functional group plays a large role in determining the properties of the compound hence the name functional group. Check out the new and improved version herehttpsyoutubeWCm3oIzfdo8Learn the basics of functional groups for your Organic Chemistry class in under 5 min.
