The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...
Transition state theory explains the dynamics of reactions. The theory is based on the idea that there is an equilibrium between the activated complex and reactant molecules. The theory incorporates concepts from collision theory, which states that for a reaction to occur, reacting molecules must collide with a minimum energy and correct ...
This reaction is important in the history of organic chemistry because it helped prove the structure of ethers. The general reaction mechanism is as follows: [3] An example is the reaction of sodium ethoxide with chloroethane to form diethyl ether and sodium chloride: C 2 H 5 Cl + C 2 H 5 ONa → C 2 H 5 OC 2 H 5 + NaCl
In 1948 Finkelstein joined the faculty of UCLA as part of the high energy theory group. [5] Several times he was on sabbatical at the Institute for Advanced Study. [4] He was a Guggenheim Fellow for the academic year 1959–1960. [6] He retired from UCLA in 1986 as professor emeritus. [5]
An example of a simple chain reaction is the thermal decomposition of acetaldehyde (CH 3 CHO) to methane (CH 4) and carbon monoxide (CO). The experimental reaction order is 3/2, [4] which can be explained by a Rice-Herzfeld mechanism. [5] This reaction mechanism for acetaldehyde has 4 steps with rate equations for each step :

The Rice–Ramsperger–Kassel–Marcus (RRKM) theory is a theory of chemical reactivity. [ 1 ] [ 2 ] [ 3 ] It was developed by Rice and Ramsperger in 1927 [ 4 ] and Kassel in 1928 [ 5 ] (RRK theory [ 6 ] ) and generalized (into the RRKM theory) in 1952 by Marcus [ 7 ] who took the transition state theory developed by Eyring in 1935 into account.
Hans Finkelstein (17 May 1885, Leipzig, Germany - December 1938) was a German chemist. He is particularly known for the Finkelstein reaction developed by and named after him. [ 1 ] [ 2 ]
