Answer:
Correct Answer: 31. (d)
Solution:
- Key idea All the reactions involved in the problem are Nucleophilic substitution of second order i.e.,
Of the reactions given
Reaction 1 in its generalised format is seen as
Reaction 2 is simple halogen exchange reaction called Finkelstein reaction. Its generalised format is
where
Reaction 3 in its generalised format seen as
Now if the given product is
and which is too enantiomerically pure i.e.
Note The configuration at carbon * atom in ’
Thus, the probable reactions will be
