Carbonyl is a small ligand so steric factors do not complicate the analysis.
2.
Usually, the more complex the reactant molecules, the lower the steric factor.
3.
Usually, the more complex the reactant molecules, the lower the steric factors.
4.
The predicted rate constant can be improved by using a better estimation of the steric factor.
5.
The interaction strength depends not only on the functional groups present in the structure of the analyte molecule, but also on steric factors.
6.
Nevertheless, some reactions exhibit steric factors greater than unity : the harpoon reactions, which involve atoms that exchange electrons, producing ions.
7.
Physically, the steric factor can be interpreted as the ratio of the cross section for reactive collisions to the total collision cross section.
8.
For asymmetric dipole-dipolarophile pairs, two electronic / stereoelectronic and steric factors contribute to the regioselectivity of 1, 3-dipolar cycloadditions.
9.
Fluorine atoms are small enough for a 1, 2-addition, while Cl 2 and Br 2 add to remote C atoms due to steric factors.
10.
However, in the early 1960s, more and more scientists were starting to think that steric factors were the driving force behind the selectivity for this reaction.
