Answer:

a) (i)

Explanation:

Racemic Mixture- It is defined as the one which has equal amount of right enantiomers to that of equal amount of left enantiomers or simply we can say is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule.

Neucleophillic Substitution- In organic part of the chemistry we see that  nucleophilic substitution is reaction in which an electron rich nucleophile selectively form bonds with or attacks the positive or partially positive charge of an atom.
