**Title: Reaction Products from Ozonolysis** **Question:** Which product(s) would form under the conditions given below? **Reaction Conditions:** 1. O₃ (ozone) 2. Me₂S (dimethyl sulfide) **Reactant Structure:** - A cyclopentene alkene. **Possible Products:** - **A.** 2-pentanone - **B.** Propanal - **C.** Formaldehyde - **D.** Cyclopentanone **Options:** - A - B - C - D - A and C - B and D - A and B **Explanation of the Reaction:** This reaction is an example of ozonolysis, which involves the cleavage of alkenes using ozone to form carbonyl compounds. In the presence of a reducing agent like dimethyl sulfide (Me₂S), the ozonide intermediate is reduced to carbonyl compounds (ketones or aldehydes). Based on the given reactant (a cyclopentene), the selection of products follows: - **D (Cyclopentanone)** as the resulting product from the cleavage and rearrangement of the cyclic alkene. Choose the correct option from the list that matches product D.

**Question:** Choose the best reagents to achieve the transformation shown below. **Diagram:** - The starting material is a molecule of 1-butene, represented with a double bond between the first and second carbon atoms of the chain. - The product is a brominated alkane, 2-bromobutane, with a bromine (Br) atom attached to the second carbon atom. **Options:** - ○ HBr - ○ HBr, ROOR - ○ Br₂ - ○ Br₂, H₂O **Explanation:** The transformation shows an addition reaction where the double bond in an alkene (1-butene) is converted into a single bond with the addition of a bromine atom at the second carbon. This is indicative of an anti-Markovnikov addition, which occurs in the presence of HBr and peroxide (ROOR). The correct choice for this transformation is thus **HBr, ROOR**.
