Compound X, C8H17Cl, is a chiral product of the radical chlorination of 4-methylheptane. X reacts in SN2 fashion with NaI in acetone to form Z, C8H17I. When the reactant is the R-enantiomer of X, only the R-enantiomer of Z is formed. Draw a structural formula for X; do not show stereochemistry.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.

The correct answer should be a.
