**Mechanism for the Reaction of Bromine with 4,4-Dimethylcyclopentene in Water**The mechanism involves the addition of bromine to 4,4-dimethylcyclopentene, resulting in different potential products depending on how bromine and water interact with the substrate. Below is a detailed description of the steps and a multiple-choice question related to the correctness of the mechanism.**Step 1:**- The reaction begins with the attack of the double bond in 4,4-dimethylcyclopentene on a bromine molecule (Br₂). - This results in the formation of a cyclic bromonium ion and the release of a bromide ion (Br⁻).- The bromonium ion has a positive charge localized on the bromine atom.**Step 2:**- Water (H₂O) approaches and attacks the more substituted carbon atom of the bromonium ion, opening the three-membered ring.- This reaction forms an intermediate with a hydroxyl group (OH) attached and a positively charged oxygen atom.**Step 3:**- A proton transfer occurs from the oxygen to a water molecule, resulting in the formation of a neutral alcohol and hydronium ion (H₃O⁺).**Graph/Diagram Explanation:**- The diagram shows the transformation from 4,4-dimethylcyclopentene to a bromonium ion, then to the intermediate, and finally to the end product, a bromohydrin, along with the generation of H₃O⁺.**Multiple-choice question:**- Which of the following statements about this mechanism is correct? - In Step 1, bromine could add to the other face of the alkene, giving a bromonium ion that is the enantiomer of the one shown. - In Step 2, water could attack the other carbon atom of the bromonium ion, leading to the enantiomer of the product shown. - This mechanism is complete and correct. - In Step 2, water could attack the bromonium ion from the other side, leading to the cis product.
