Interpretation Introduction

(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 that the main chain or ring of carbon atoms in the compound. The suffix to the 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 atoms. If the sequence of priority order 123 is clockwise, the absolute configuration is R, and if it is counterclockwise, the absolute configuration is S.

Concept introduction:

The root name in the given IUPAC name suggests that 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 paranthesis 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 the atomic number of directly bonded atom. If the sequence of priority order 123 is clockwise, the absolute configuration is R, and if it is counterclockwise, the absolute configuration is S.
