(a)
Interpretation:
The IUPAC name for the given compound with appropriate stereochemical designation is to be assigned.
Concept introduction:
In naming organic compounds, the
The stereochemical designation and the locators are enclosed in parenthesis at the very beginning of the name. The stereochemistry at the chiral center is determined by assigning the priorities to the groups attached to the chiral center on the basis of
Answer to Problem E.46P
The name of the given compound is
Explanation of Solution
The given compound is:
In this compound, the highest priority functional group is ketone, thus, the suffix ‘one’ is added to the root name. The main chain is of six carbon atoms that indicates the root name as “hexan”. The substituents are
The ketonic carbon is numbered as
The fourth group, attached to chiral center
In the order of decreasing sequence rule
The fourth group attached to the chiral center
In the order of decreasing sequence rule,
The fourth group, attached to chiral center
In the order of decreasing sequence rule
Hence the given compound is named as:
The given compound is named by identifying the main chain containing the functional group and the substituents attached with appropriate stereochemistry.
(b)
Interpretation:
The IUPAC name for the given compound with appropriate stereochemical designation is to be assigned.
Concept introduction:
In naming organic compounds, the functional groups other than highest priority functional groups are treated as substituents. The root name is established by identifying the longest carbon chain or a ring containing functional group. Remove the “e” from the normal ‘ane’, ‘ene’, or ‘yne’ ending and add the suffix that corresponds to the highest-priority functional group. Prefixes are used to denote number of identical substituents. Number the carbon chain in a way that the functional group and the substituents attached get the lowest number. The position of functional group and substituents on parent chain or ring is indicated by the respective locant number just before the suffix. The substituents are written in alphabetical order when writing the IUPAC name.
The stereochemical designation and the locators are enclosed in parenthesis at the very beginning of the name. The stereochemistry at the chiral center is determined by assigning the priorities to the groups attached to chiral center on the basis of atomic number of directly bonded atom. If the sequence of priority order

Answer to Problem E.46P
The name of given compound is:
Explanation of Solution
The given compound is:
In this compound, the main chain is of seven carbon atoms which indicates the root name as ‘heptane’. The highest priority functional group is ketone. The chain has three carbonyl groups, therefore, the suffix ‘trione’ is added to the root name. The substituents are
The ketonic carbons are numbered as
The fourth group attached to chiral center
In the order of decreasing sequence rule
The fourth group attached to chiral center
In the order of decreasing sequence rule
Hence, the given compound is named as:
The given compound is named by identifying the main chain containing functional group and the substituents attached with appropriate stereochemistry.
