The effect of the tert-butyl group on the progress of a chemical reaction is called the Thorpe–Ingold effect illustrated in the Diels-Alder reaction below. Compared to a hydrogen substituent, the tert-butyl substituent accelerates the reaction rate by a factor of 240. [2] tert-Butyl effect. The tert-butyl effect is an example of steric hindrance.
A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [1] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.
Above: Newman projection; below: depiction of spatial orientation. In chemistry, rotamers are chemical species that differ according to rotations about a single bonds. Various arrangements of atoms in a molecule that differ by rotation about single bonds can be referred to as different conformations.

n-Butylbenzene is the organic compound with the formula C 6 H 5 C 4 H 9.Of two isomers of butylbenzene, n-butylbenzene consists of a phenyl group attached to the 1 position of a butyl group.
A group of Republicans want Donald Trump to end it, saying it's government overreach. More than two dozen House Republicans are asking President-elect Donald Trump to terminate the Internal ...
The iodine group is homolytically removed to form an aryl radical by a tributyltin hydride/triethylboron/oxygen mixture as in the Barton–McCombie reaction. Although the hindered rotation is now removed in the aryl radical, the intramolecular reaction with the alkene is so much faster than is rotation of the carbon–nitrogen bond that the ...
