(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 functional group. The prefix with locant number indicates the number of substituents and their respective position at the main chain or 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 the chiral center on the basis of
