Suffix carboxylic acid

When a carboxyl group is attached to a ring the parent ring is named (retaining the final e) and the suffix carboxylic acid is added as shown m entries 8 and 9... 

The suffixes -oic acid, -al, -amide and -nitrile are used to name acyclic compounds having one or two characteristic groups. Locants are not necessary, as these groups must be at the end of a chain. The suffixes -carboxylic acid, -carbaldehyde, -carboxamide and -carbonitrile are used when more than two groups are attached to chains or one or more groups are attached to cycles. 

Chlorocyclopentanecarboxylic acid (In similar fashion to the use of the -carbaldehyde suffix in naming aldehydes, cyclic compounds with the carboxy group attached to the ring use the name of the ring with the suffix -carboxylic acid.)... 

Occasionally in the literature, the carboxyl unit is regarded as a group substituted for hydrogen. In this case, the number 1 location is moved one position away from the reactive end, and the suffix carboxylic acid is added ... 

Compounds that have a carboxylic acid bonded to a ring are named by using the suffix -carboxylic acid. 

Vhen-CO2H is a substituent of a ring, the suffix -carboxylic acid is used the carboxyl carbon is not numbered in this system. 

When the - COCl group is bonded to a ring Change the suffix -carboxylic acid to -carbonyl chloride. 

Alternatively, compounds that have a -COOH group bonded to a ring are named using the suffix -carboxylic acid. The COOH carbon is attached to Cl and is not itself numbered in this system. 

Special case When the chain numbering cannot include the carbon of the carboxylic acid, the suffix "carboxylic acid" is used CHO... 

Carboxylic acids are almost always named using a suffix. The suffix oic acid is attached to the name for the longest continuous carbon chain. If the acid group is attached to a ring the suffix carboxylic acid is used. 

The carboxylic acid derivatives of cycloalkanes are named by adding the suffix carboxylic acid to the name of the cycloalkane or substituted cycloalkane. The carboxyl group is always on carbon-1 and other substituents are named and numbered as usual. 

When an acid halide moiety is connected to a ring, the suffix carboxylic acid is replaced with carbonyl halide , for example. 

Name compounds that have a —COOH group bonded to a cycloalkane ring as derivatives of the cycloalkane with the suffix carboxylic acid. The ring atom to which the carboxyl group is attached is C-1. Do not include this number in the name.
