Neglecting the chain ends, poly(a-olefins) feature a C s symmetry and therefore possess a pseudo-mirror plane (Fig. 1).5 Because of the recent development of single-site catalysts for

WebOct 29, 2024 · Because chirality is one of the most important concepts in chemistry, several definitions of a chiral molecule are known. The simplest definition is that a chiral molecule is a molecule having (a) carbon atom (s) to which four different groups are attached. WebCryptochirality A second concept—that of cryptochirality-also illustrated by Mislow and... The difference in the ligands of each tertiary atom is due mainly to the different length of chain segments to which it is bonded.
