DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The effect of the shape of a Me group on reactivity (an effect which cannot be accounted for by considering a Me group as a spherical substituent) was studied in the kinetics of alkylation of substituted pyridines and barriers to rotation and ground state conformations of an iso-Pr group attached to a planar framework. The perturbation of a Me group by an o-Me group is accounted for by a unique conformational explanation which involves the polyhedral shape of the Me group. .
