To determine which reaction is correct, we need to examine each option in relation to chemical principles such as reaction mechanisms, thermodynamics, or conservation of mass and charge. Let's analyze the options provided and justify the correct answer.
Firstly, we need to consider the reaction mechanisms. Analyze each reaction for correct conservation of mass and charge. Verify if the products are feasible given the starting materials and reaction conditions.
Review the balanced nature of the reactions. Each chemical equation should have the same number of each type of atom on both sides of the reaction.
Consider the practical validation of these reactions if any of them are based on well-known reactions in chemistry or are covered in the exam syllabus.
Therefore, Reaction 2 as depicted in "Fig 2" is correct. Typically, the logic behind selecting this option would be because it adheres to the established rules of chemistry principles mentioned above.
Conclusion: After reviewing each option through these criteria, "Fig 2" aligns correctly with chemical reaction principles and has been identified as the correct response. To master similar questions, focus on mastering fundamental reactions, understanding balancing techniques, and familiarizing yourself with common reaction types.

Approach Solution -2
The correct reaction involves the substitution of an alkyl halide with HI (Hydrogen iodide), which proceeds with the formation of a halide and is a typical example of nucleophilic substitution. This reaction follows Markovnikov’s addition rule where the halide (in this case, iodine) adds to the more substituted carbon of the alkyl halide.
