The image presents a chemical reaction question, which asks to identify the major organic product formed under specific conditions. The reactant is propene, represented as a three-carbon alkene with a double bond.**Reagents and Conditions:**1. BH₃·THF (Borane in Tetrahydrofuran)2. NaOH, H₂O₂ (Sodium Hydroxide, Hydrogen Peroxide)**Reaction Description:**This is a hydroboration-oxidation reaction, a common method for converting alkenes to alcohols.**Product Choices:**Four structural options are provided for selection:1. A primary alcohol with the hydroxyl group on the terminal carbon.2. A secondary alcohol with the hydroxyl group on the middle carbon.3. An organoborane intermediate with BH₂ attached to the terminal carbon.4. A diol containing two hydroxyl groups.The correct choice for this reaction is the primary alcohol, where the hydroxyl group is added to the less substituted carbon, illustrating anti-Markovnikov addition typical of hydroboration-oxidation reactions. **Explanation of Reaction and Potential Major Products:**In this exercise, we are asked to determine the major product of the given reaction, where a dibenzyl is exposed to osmium tetroxide (OsO₄) followed by sodium bisulfite (NaHSO₃) in water. This process typically results in the conversion of alkenes to diols by syn-dihydroxylation.### Reaction Details:- **Reagents:** 1. **OsO₄** (Osmium tetroxide) 2. **NaHSO₃, H₂O** (Sodium bisulfite in water)- **Mechanism:** The osmium tetroxide adds to the double bond in a syn addition manner, leading to the formation of a cyclic osmate ester intermediate, which is subsequently hydrolyzed by sodium bisulfite to give a vicinal diol.### Options for Major Products:1. **Option 1:** - Structure: Two adjacent carbon atoms each bonded to a hydroxyl group, showing syn addition as both -OH groups are on the same side. Phenyl groups (Ph) are also present, indicating the presence of benzene rings.2. **Option 2:** - Structure: Similar to option 1, with stereochemistry indicating syn addition but with different orientation. Phenyl groups are shown.3. **Option 3:** - Structure: An epoxide ring is suggested here. This indicates a different pathway and is not the expected outcome with OsO₄.4. **Option 4:** - Structure: Suggests the formation of an open chain with additional phenyl groups which is unlikely under these conditions.5. **Option 5:** - Structure: Another epoxide, similar to option 3, which is less likely here.6. **Option 6:** - Statement: No reaction under these conditions or the correct product is not listed.### Conclusion:- **Expected Outcome:** This reaction most likely leads to a syn-diol formation on the alkenes, specified in options 1 or 2. The reaction condition and reagents strongly support syn addition of hydroxyl groups.
