(a)
Interpretation:
The structure from the given IUPAC name with appropriate stereochemistry is to be drawn.
Concept introduction:
The root name in the given IUPAC name suggests the main chain or ring of carbon atoms in the compound. The suffix to root name indicates the highest priority
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.48P
The structure for IUPAC name
Explanation of Solution
The given IUPAC name is
The root name in this IUPAC name ‘cyclopentan’ represents the main ring of five carbon atoms. The suffix ‘one’ represents the highest priority functional group -
The structure has three chiral centers,
Thus, for absolute configuration
The absolute configuration at
Thus, for absolute configuration
The absolute configuration at
Thus for absolute configuration
Hence, the structure for is
The structure for the given IUPAC name is drawn by identifying the highest priority functional group from the suffix, main chain from root name, and the position for the substituents from the locant with appropriate stereochemistry.
(b)
Interpretation:
The structure from the given IUPAC name with appropriate stereochemistry is to be drawn.
Concept introduction:
The root name in the given IUPAC name suggests the main chain or ring of carbon atoms in the compound. The suffix to root name indicates the highest priority functional group. The prefix with locant number indicates the number of substituents and their respective position at the main chain or at a ring of carbon atoms.
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
