RESULTS Exptl m.p. ( o C) Lit. m.p. ( o C) Lit. source Yield (g) Appearance % Yield cis-Norbornene-5,6- endo-Dicarboxylic Acid 153-156 °C 165 °C Williamson 0.5062 White powder 29.12 % Error calculation To calculate the % error, first the average experimental m.p. was calculated. (156+153) / 2 = 154.5 °C Then, this experimental melting point was compared to the accepted melting point found in the Williamson literature. (165-154.5 °C) / 165 °C = 6.36 % error
