A molecule (“P”) on treatment with acid undergoes rearrangement and gives (“Q”). (“Q”) on ozonolysis followed by reflux under alkaline condition gives (“R”). The structure of (“R”) is given below:
The structure of (“P”) is:
Which of the following compound can give positive iodoform test when treated with aqueous KOH solution followed by potassium hypoiodite.
can be subjected to Wolff-Kishner reduction to given 
will react with \( \mathrm{NaOH} \) and also with Tollen’s reagent.
will undergo self aldol condensation very easily.
(Where Et is \( -\mathrm{C_2H_5} \)). 
undergoes intramolecular aldol condensation, the major product formed is:
under Clemmensen reduction conditions will give 
under Clemmensen reduction conditions will give 
\( (x) \). He thought of preparing the molecule using an aldol condensation reaction. He found a few cyclic alkenes in his laboratory. He thought of performing ozonolysis reaction on alkene to produce a dicarbonyl compound followed by aldol reaction to prepare “\( x \)”. Predict the suitable alkene that can lead to the formation of “\( x \)”.
