(a)
Interpretation: To write the IUPAC names for the given carbonyl compounds.
Concept Introduction: Carbonyl group is the combination of carbon and oxygen double bound together. If the general formula of a carbonyl compound is
(a)
Answer to Problem 21LC
The IUPAC name of the given compound is Propan-1-al.
Explanation of Solution
In the given compound the longest carbon chain contains three carbons and the
(b)
Interpretation: To write the IUPAC names for the given carbonyl compounds.
Concept Introduction: Carbonyl group is the combination of carbon and oxygen double bound together. If the general formula of a carbonyl compound is
(b)
Answer to Problem 21LC
The IUPAC name of the given compound is Hexan-3-one.
Explanation of Solution
The given compound contains the longest carbon chain with six carbons and the carbonyl group is present between the carbon chain. This shows that the carbonyl group that is present is a ketone and the carbonyl group is considered the third carbon. Therefore, the name is given as Hexan-3-one.
(c)
Interpretation: To write the IUPAC names for the given carbonyl compounds.
Concept Introduction: The nomenclature of carboxylic acids includes the selection of the longest carbon chain. The functional group should be numbered in such a way that it gets the lowest number. The naming will include the substituent followed by the longest chain containing the functional group with the suffix “-oic acid”.
(c)
Answer to Problem 21LC
The given IUPAC name is Pentan-1-oic acid.
Explanation of Solution
In the given compound the longest carbon chain contains five carbons. The functional group present in this case is

- Soap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups.
