Please don't provide hand written solution..... **Question 19:** *What conditions given below would you predict to generate the highest amounts of the product shown?*[Reaction Scheme: A cyclohexane ring with an OTosylate (OTs) group is converted to a cyclohexene with a double bond. The reaction conditions are questioned.](a) NaOMe in MeOH. (b) NaSMe in MeOH. (c) LDA in THF. (d) NaSMe in DMF. **Answer:**- **First choice: ______**- **Second choice: ______** **Explanation of Diagrams:**There are two chemical structures displayed. The first structure is a cyclohexane ring with a tosylate group (OTs) attached. This indicates that a substitution reaction or elimination process may be used to convert this compound into the second structure.The second structure is a cyclohexene, showing that a double bond is present, suggesting the product of an elimination reaction leading to an alkene.The task is to select the best conditions from the options provided that would favor the formation of the cyclohexene product. The options represent different base and solvent conditions that could potentially drive an elimination reaction.

Here alkene is formed by an elimination reaction. Alkene formed here is less substituted for Hoffmann products. Best reagent to use for Hoffmann elimination is bulky base.Here it is clearly evident that bulky base is LDA.So correct answer will be option C i.e LDA in THF.So correct answer will be option C i.e LDA in THF.
