Ans 31.

The first structure is formed as the product of diels alder reaction of hexa chlorocyclopentadiene.

The reaction involves halogen containing alkenes as dienophiles and occurs only when atleast one hydrogen atom is attached to the double bond.

The reaction with thiones will yield the formation of [2+4] cycloadducts like this.
