When carboxylic group is attached directly to benzene ring the acid is called?
The acid with the carboxyl group attached directly to a benzene ring is called benzoic acid (C6H5COOH).
How do you name aromatic compounds with multiple substituents?
Alkyl groups are named according to the alkane series convention ending with -yl: methyl (for a single carbon), ethyl (for two carbons), propyl (for three carbons), etc. If the substituent contains more than six carbons, the alkane portion is named first, and the aromatic ring portion is added as a suffix.
How do you name an aldehyde with a carboxylic acid?
In common names of aldehydes, carbon atoms near the carboxyl group are often designated by Greek letters. The atom adjacent to the carbonyl function is alpha, the next removed is beta and so on.
How do you name an aldehyde with benzene rings?
If the aldehyde moiety (-CHO) is attached to a ring the suffix –carbaldehyde is added to the name of the ring. The carbon attached to this moiety will get the #1 location number in naming the ring. Aldehydes take their name from their parent alkane chains. The -e is removed from the end and is replaced with -al.
How do you name aromatic carboxylic acids?
The carboxyl carbon is always numbered “1” but the number is not included in the name. Name the substituents attached to the chain in the usual way. Aromatic carboxylic acids (i.e., with a CO2H directly connected to a benzene ring) are named after the parent compound, benzoic acid.
How do you name compounds with benzene?

How do you name compounds containing benzene?
Simple Benzene Naming The general format for this kind of naming is: (positions of substituents (if >1)- + # (di, tri.) + substituent)n + benzene. For example, chlorine (Cl) attached to a phenyl group would be named chlorobenzene (chloro + benzene).
How do you name a carboxylic acid?
In general, carboxylic acids are named based on the number of carbons in the longest continuous chain, including the carboxyl group (-COOH). The suffix of this carbon chain is then replaced, as carboxylic acids always end in “-oic acid.” An example is CH2O2, in which the longest continuous carbon chain is a methane.
