What wold you prodict for the relative reactivity of 4-trifluoromehylbenzaldehyde in this aldol condensation reaction? Explain. (Compare to benzaldehyde, 4-methylbenzaldehyde, 4-methoxybenzaldehyde, 4-chlorobenzaldehyde, and 2-nitrobenzaldehyde.
If 75 g of liquid water (C = 4.18 J/g-oC) in a calorimeter changes temperature from 25°C to 75°C, how much heat was transferred? Use the equation C = q/mT.
In the dehydration experiment, several ml of saturated sodium chloride is used to transfer crude product after the initial distillation. Why is saturated sodium chloride, rather than pure water, used for this experiment.
