Question

Write the IUPAC name of:
A.$C{H_3}COC{H_2}C{H_3}$
B.$C{H_3} - CH(OH) - C{H_3}$
C.$HCOOH$
D.$CH3COOC{H_3}$

Answer 1

Hint:We know that in chemical nomenclature, the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds. The IUPAC system of nomenclature assigns a characteristic suffix -al to aldehydes. The IUPAC system of nomenclature assigns a characteristic suffix of -one to ketones. A ketone carbonyl function may be located anywhere within a chain or ring, and its position is usually given by a location number.

Complete answer:
The chain numbering normally starts from the end nearest the carbonyl group. Also, there is a common method for naming aldehydes and ketones. For aldehydes common parent chain names, similar to those used for carboxylic acids, are used and the suffix –aldehyde is added to the end.
The IUPAC name of the following compound are:
A.$C{H_3}COC{H_2}C{H_3}$
Its IUPAC name is 2-propanone
B. $C{H_3} - CH(OH) - C{H_3}$
Its IUPAC name is 2-propan-2-ol
C. $HCOOH$
 Its IUPAC name is methanoic acid
D. $CH3COOC{H_3}$
Its IUPAC name is methyl ethanoate or methyl acetate.

Note:
Aldehydes and ketones contain the carbonyl group. Aldehydes are often called the formyl or methanoyl group. Aldehydes derive their name from the dehydration of alcohols. Aldehydes contain the carbonyl group bonded to at least one hydrogen atom. Ketones contain the carbonyl group bonded to two carbon atoms. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen, alkyl or aryl substituents. If at least one of these substituents is hydrogen, then it is an aldehyde and if neither is hydrogen, then the compound is a ketone.
