The ensuing reaction results in the cleavage of the ether or the ester into an alkyl iodide and respectively an alcohol or a carboxylic acid. Zeisel determination By heating this mixture, the gases are allowed to come into contact with a piece of paper higher up the test tube saturated with silver nitrate .
This compound is known as 2,3,3-trimethylpentane. Here three identical alkyl groups attached to carbon atoms 2, 3, and 3. Here three identical alkyl groups attached to carbon atoms 2, 3, and 3. The numbers are included in the name to avoid ambiguity about the position of the groups, and "tri" indicates that there are three identical methyl groups.
Hagemann's ester, ethyl 2-methyl-4-oxo-2-cyclohexenecarboxylate, is an organic compound that was first prepared and described in 1893 by German chemist Carl Hagemann. The compound is used in organic chemistry as a reagent in the synthesis of many natural products including sterols , trisporic acids , and terpenoids .

Gutmann, a chemist renowned for his work on non-aqueous solvents, described an acceptor-number scale for solvent Lewis acidity [4] with two reference points relating to the 31 P NMR chemical shift of Et 3 PO in the weakly Lewis acidic solvent hexane (δ = 41.0 ppm, AN 0) and in the strongly Lewis acidic solvent SbCl 5 (δ = 86.1 ppm, AN 100).
It can be produced by a Friedel-Crafts alkylation between 1-chlorohexane and benzene., [1] or by the reaction of benzene and 1-hexene with various acid catalysts such as antimony pentafluoride, [2] scandium(III) triflate, [3] and phosphoric acid.
The hexyl derivative is common test substrate because it is conveniently volatile. It undergoes deprotonation at C-3 and C-1 with butyl lithium: HC 2 C 4 H 9 + 2 BuLi → LiC 2 CH(Li)C 3 H 7 + 2 BuH. This reaction allows alkylation at the 3-position. [2] Catechol borane adds to 1-hexyne to give the 1-hexenyl borane. [3]
3-Ethylpentane (C 7 H 16) is a branched saturated hydrocarbon. It is an alkane, and one of the many structural isomers of heptane, consisting of a five carbon chain with a two carbon branch at the middle carbon. An example of an alcohol derived from 3-ethylpentane is the tertiary alcohol 3-ethylpentan-3-ol. [3]
