Suppose Cloves contain two principal essential oils, caryophyllene and eugenol. A student implementing a steam distillation using cloves obtained a mixture of these two oils in the distillate. Define how the student could separate also isolate the two essential oils using liquid extraction. Phenols are moderately acidic moreover can be deprotonated by NaOH.
Classify each of the following molecules as polar or nonpolar: a) GeH4; b) I2; c) CF3Cl; d) PCl3; e) BCl3; f) SCl2.
After the reaction has reached equilibrium, the absorbance of the product C is measured and its concentration is determined to be 0.00745 M. Calculate the equilibrium constant for this reaction.
