Steric effects arise from the
spatial arrangement of atoms. When
atoms come
close together there is
generally a rise in the
energy of the molecule. Steric...
- The
steric factor,
usually denoted ρ, is a
quantity used in
collision theory. Also
called the
probability factor, the
steric factor is
defined as the ratio...
- der
Waals strain is also
called Van der
Waals repulsion and is
related to
steric hindrance. One of the most
common forms of this
strain is
eclipsing hydrogen...

ethanol produces the
Zaytsev product with
moderate selectivity. Due to
steric interactions, a
bulky base – such as pot****ium tert-butoxide, triethylamine...

metal identity and
electron density, (2)
sterics, (3) parti****ting ligands, (4)

- a
steric 5-cube or (
steric 5-demicube or
sterihalf 5-cube) is a
convex uniform 5-polytope.
There are
unique 4
steric forms of the 5-cube.

-
formed by its
nonbonding valence electrons is
known as the
central atom's
steric number. The
electron pairs (or
groups if
multiple bonds are present) are...
- A
sterimol parameter is a set of
vectors which describes the
steric occupancy of a molecule.
First developed by
Verloop in the 1970s.
Sterimol parameters...
- form
adducts which exhibit steric effects. For example:
trimethyltin chloride, when
reacting with
diethyl ether,
exhibits steric repulsion between the methyl...

calcium stearate,
which functions as a
release agent.
Steric acid can be
converted to zinc stearate,
which is used as a
lubricant for...
