When aqueous CuCl, is reacted with excess sodium diethyl dithiophosphate, Na S2P(OEt),, a redox reaction occurs, producing Na [Cu(S2P(OEt)2)2], a white copper(I) compound. The concurrent oxida- tion of the diethyl dithiophosphate anion produces a byproduct having the formula CgH20P2S404- a) Draw the structure of the diethyl dithiophosphate anion. b) Draw the structure of the copper complex (which has a tetrahedral coordination sphere). c) Draw the structure of the CH20P2S404 byproduct. Hint: To figure out the likely structure of this oxidation product, note what happens to thiourea when it becomes oxidized, eq. (4).
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
