Question

The major products P and Q of the following transformations are 

Hint:

Elimination reactions often proceed via dehydrohalogenation to form double bonds, especially when a strong base is used.

Answer 1

Step 1: Understanding the reaction.
This transformation involves a base-induced reaction on a bromo-substituted carboxylic acid. The reaction is likely to involve an elimination process (such as the formation of an alkene or the removal of the halide) facilitated by the base.
Step 2: Identifying the products.
- Product P is likely the result of an elimination (dehydrohalogenation) reaction, where the bromine atom is replaced by a double bond, forming a conjugated system. - Product Q could involve a further transformation such as an esterification or other reaction with the base.
Step 3: Conclusion.
The correct products corresponding to these transformations are as shown in option (D).
Final Answer: \[ \boxed{\text{Product P and Q are as shown in Option (D)}} \]
