Abstract

Cyclopentadiene is a five membered cyclic organic compound with molecular formula C5H6 abbreviated as CpH. The pKa of CpH is 15. It is probably known world strongest carbon acid after Fluoradene (pKa is 11.0 in DMSO, ref. 17) with only carbon-hydrogen framework without any hetero atoms. It is highly reactive diene, and dienophile can undergo dimerization via Diels–Alder Reaction to dicyclopentadiene (DCPD). In the present work we have tried to characterize the percentage mole fraction of the dimerization product by a physical constant Refrachor (F).
