(a)
Interpretation: The IUPAC and common name (if any) of the following compound should be determined:
Concept Introduction: An organic compound in which carboxy
The reaction which results in the formation of amide along with water on heating acids with
So, in order to give the IUPAC name to the amides, the rules for naming carboxylic acid is followed and -oic acid of the carboxylic acid is replaced by amide.
In order to give the name to the amide group, the following steps are followed:
- The parent (longest)
alkane chain is named as for carboxylic acids. - The -oic acid in the name is changed to -amide.
- The numbering of the chain is done in such a way that amide group and substituents gets the smaller number.
- N-alkyl is used to show each alkyl group bonded to -N atom in the name for secondary and tertiary amides.
For number of carbons atoms chain, the prefix is given as:
Carbon-1 meth
Carbon-2 eth
Carbon-3 prop
Carbon-4 but
Carbon-5 pent
Carbon-6 hex
Carbon-7 hept
Carbon-8 oct
Carbon-9 non
Carbon-10 dec
In order to write the common name of the amides, the common of acids are written from which the amide has been formed by replacing -oic acid in name from -amide.
(b)
Interpretation: The IUPAC and common name (if any) of the following compound should be determined:
Concept Introduction: An organic compound in which carboxy functional group that is -COOH is bonded to the carbon atom is said to be a carboxylic acid. The general formula for carboxylic acid is RCOOH or RCO2H. When -OH (hydroxyl group) of the carboxylic acid is replaced by nitrogen (-N) then it results in the formation of an amide.
The reaction which results in the formation of amide along with water on heating acids with amine or ammonia is said to be amidation.
