2 Answers
Let's do them one by one
Explanation:
A: propanal, an aldehyde, functional group -CHO
B: pentanoic acid, a carboxylic acid, functional group -COOH
C: 2-methyl butan-2-ol a (tertiary) alcohol, functional group -OH
D: methoxy ethane, an ether, functional group -O-
See explanation
Explanation:
A is an aldehyde as it has the functional group -CHO. There are three carbon atoms so the name of this substance is propanal.
B is a carboxylic acid as it has the functional group -COOH. There are five carbon atoms so its nomenclature is pentanoic acid.
C is an alcohol as it has an -OH group. It is on the second carbon and there is branched methyl group on the same carbon atom. Therefore, its nomenclature is 2-methylbutan-2-ol. Remember: if there are branches, use the smallest carbon atom number.
D has the functional group -O- showing that it is an ether. The nomenclature is methoxy ethane.
