For the reaction below:Draw the major organic structure. This image depicts a chemical reaction involving an epoxide. The structure on the left is an epoxide with an oxygen atom forming a three-membered ring with two adjacent carbon atoms. The stereochemistry is shown with wedge and dash bonds, indicating the three-dimensional arrangement of the groups around the carbon atoms. The substituents include a hydrogen (H), two methyl groups (CH₃), and an ether oxygen (O).The arrow indicates a chemical reaction, with conditions specified above and below it. Above the arrow is "CH₃ONa," which is sodium methoxide, a strong base and nucleophile. Below the arrow is "CH₃OH," methanol, a solvent. This suggests a nucleophilic ring-opening reaction catalyzed by sodium methoxide in the presence of methanol.In this reaction, the epoxide is likely to open up, resulting in the formation of a new product where the nucleophile, methoxide, attacks the less hindered carbon atom in the epoxide ring. This is a typical reaction mechanism for an epoxide under basic conditions.

In the reaction between an epoxy and CH3ONa i.e nucleophile, the nucleophile attacks on the epoxy from the less crowded position and open the epoxy ring via SN2 mechanism. And after the ring opening, proton transfer step takes place to produce the final major product. Please find below the reaction mechanism taking place along with the major product.
