Question

Which of the following statements are correct about the following reactions?

• A. Reaction 1 proceeds by $S_{N}2$ and reaction 2 by $S_{N}1$ mechanism
• B. Reaction 1 proceeds by $S_{N}1$ and reaction 2 by $S_{N}2$ mechanism.
• C. The products (B) and (C) are
  
  The products (B) and (C) are respectively.
• D. The products (B) and (C) are
  

Answer 1

Answer: (A), (C)

The products (B) and (C) are


The products (B) and (C) are respectively.
5M of NaOH is a strong and smaller size nucleophile, thus, it proceeds through $S_{N}2$ mechanism to give a inversion comfiguration product.

Thus, it produces a $(-)$ product =

For reaction 2:
Addition of dil. NaOH makes it follow a $S_{N}1$ mechansim.

Thus, it forms racemic mixture
