c) The species [(n°-CSHS)Ru(CO(PMe3)]2 has v(CO) bands at 1927 and 1900 cm-! Propose a structure for this species consistent with the IR data and explain your reasoning.
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.
Inorganice chemistry
Part C only, thanks.
![Questions about organometallic complexes.
a) Transition metal species are classified as Werner or organometallic complexes:
Complex
Werner
Organometallic
Metal Ox. State
high
low
Example Ligand
NH,
CO
Electrons
12-22
18
In organometallic complexes briefly explain how the oxidation state of the metal
determines the type of ligand.
b) Provide the required information regarding the following organometallic
compounds.
(n²-C2H4)M(CO);
Missing 2nd-row transition metal M:
XH(CO)s
Missing 1-row transition metal X:
[(n°-CSH5)Re(CO)3]*
Charge on complex z:
