Question

Predict major products in the following reactions.

Answer 1

Step 1- In the presence of $R_{2}Li/Cu$ (Corey-house synthesis reagent) Ketone will form as the methyl group added.

Step 2- Hydrolysis of a compound will lead in the further product,

Step 3- As the two $OH$ group can't be at same position so $H_{2}O$ will remove that results in the final product.
