2,2,4,4-Tetramethyl-3-t-butyl-pentane-3-ol or tri-tert-butylcarbinol is an organic compound with formula C 13 H 28 O, ((H 3 C) 3 C) 3 COH, or t Bu 3 COH. [1] It is an alcohol that can be viewed as a structural analog of a tridecane isomer ( 2,2,4,4-tetramethyl-3- t -butylpentane ) where the central hydrogen has been replaced by a hydroxyl group ...
[2] [3] [4] The aldol reaction is paradigmatic in organic chemistry and one of the most common means of forming carbon–carbon bonds in organic chemistry . [ 5 ] [ 6 ] [ 7 ] It lends its name to the family of aldol reactions and similar techniques analyze a whole family of carbonyl α-substitution reactions , as well as the diketone ...
The kinetic order of any elementary reaction or reaction step is equal to its molecularity, and the rate equation of an elementary reaction can therefore be determined by inspection, from the molecularity. [1] The kinetic order of a complex (multistep) reaction, however, is not necessarily equal to the number of molecules involved.
The Ph 3 C-H bond is relatively weak, with a bond dissociation energy (BDE) of 81 kcal/mol, or about 24 kcal/mol less than methane. [4] Correspondingly, triphenylmethane is mildly acidic, with a pK a of 33.297.
Figure 2 shows a scanning tunneling microscopy topographic image of a step edge that shows many of the features in Figure 1. Figure 3 shows a crystal surface with steps, kinks, adatoms, and vacancies in a closely packed crystalline material, [3] which resembles the surface featured in Figure 2. Although intuitively evident, it has only recently ...
2,4-Dimethylpentane is an alkane with the chemical formula [(H 3 C) 2 CH] 2 CH 2. This colorless hydrocarbon is produced in large quantities in oil refineries. It results from the alkylation of isobutane by propylene. [1] Often referred to as "alkylate", it is blended with other gasoline components to give a high octane fuel.
The simplest case refers to the formation of a strictly linear polymer by the reaction (usually by condensation) of two monomers in equimolar quantities. An example is the synthesis of nylon-6,6 whose formula is [−NH−(CH 2) 6 −NH−CO−(CH 2) 4 −CO−] n from one mole of hexamethylenediamine, H 2 N(CH 2) 6 NH 2, and one mole of adipic acid, HOOC−(CH 2) 4 −COOH.
The equation above can also be used for a monofunctional additive which is the following, = (+) where N B is the number of monofunction molecules added. The coefficient of 2 in front of N B is require since one B molecule has the same quantitative effect as one excess B-B molecule. [15]
