Head-to-tail Polymerization Of Propylene Is Observed With The [cp2zr(

1.	Head-to-tail Polymerization Of Propylene Is Observed With The [cp2zr(r)]+ Catalyst. Explain This Result On The Basis Of Molecular-level Interactions.
Answer» Each INCOMING propylene molecular orients with its methyl group in toward R, rather than out toward cp, in order to avoid unfavorable CONTACTS with the bulky cp's. When the R group migrates to propylene, it migrates to the CLOSER olefinic CARBON, which is always the one bearing the methyl group (the "b carbon"). Each incoming propylene molecular orients with its methyl group in toward R, rather than out toward cp, in order to avoid unfavorable contacts with the bulky cp's. When the R group migrates to propylene, it migrates to the closer olefinic carbon, which is always the one bearing the methyl group (the "b carbon").
