Analysis of 3-ethyl-3-buten-2-ol gave C, 72.13%; H, 11.92%. Calculate the percent deviation of these results from the theoretical values for C and H. When 6-chloro-2-methyl-3-cyclohexenol was submitted for elemental analysis, the results were C, 51.07%; H, 7.96%; Cl, 21.53%. Are these values within the required ±0.4% of theoretical? If not calculate the apparent empirical/molecular formula and suggest the identity of the contaminant.
