The rates of solvolysis of propylene and cyclopropane in 6.49 M H 2 SO 4 have been measured as a function of temperature. From the data, calculations of the relative heats of formation in solution of the 2‐propyl cation and protonated cyclopropane have been made. The heat of formation of protonated cyclopropane has been found to be 6.4 kcal/mol greater than that of the 2‐propyl cation. The implications of this result are discussed.
