Answer:
C₄H₉Br + 2H₂O → Br⁻ + C₄H₉OH + H₃O⁺
It's basically a dissolution of C₄H₉Br in H₂O reaction.
Explanation:
C₄H₉Br → C₄H₉⁺ + Br⁻
C₄H₉⁺ + H₂O → C₄H₉OH₂⁺
C₄H₉OH₂⁺ + H₂O → C₄H₉OH + H₃O⁺
Summing up all of the reactions, as they are all balanced individually
C₄H₉Br + C₄H₉⁺ + H₂O + C₄H₉OH₂⁺ + H₂O → C₄H₉⁺ + Br⁻ + C₄H₉OH₂⁺ + C₄H₉OH + H₃O⁺
Then, the intermediates that occur on both sides cancel out, to give
C₄H₉Br + H₂O + H₂O → Br⁻ + C₄H₉OH + H₃O⁺
Summing the two molecules of H₂O, the balanced equation becomes
C₄H₉Br + 2H₂O → Br⁻ + C₄H₉OH + H₃O⁺
