Enantiomer of cis-1-chloro-3-methylcyclopentane

Draw the enantiomer of cis-1-chloro-3-methylcyclopentane which is R at C-1.

1) What is the configuration of this molecule at C-3 (R and S)?

2) When cis-1-chloro-3-methylcyclopentane and trans-1-chloro-3-methylcyclopentane are treated with sodium iodide in aqueous acetone, their rates of substitution are strikingly different. Explain clearly why this is so.

Solution Summary

Solution shows how to draw molecule at C-3 as well as explaining why this and another molecule differ in substitution rates after a treatment with sodium iodide and aqueous acetone.
