The following is a nucleophilic substitution reaction of R-3-chloro-2-methylhexane with CN. The optical rotation of the solution after the reaction was complete was 0.0° CH$_3$ H$_2$ H$_3$C---C---C---C---CH$_3$ \text{ | | |} \text{ H$_2$ Cl H} + $^-$C$\equiv$N The mechanism for this reaction is S$_N$1 Draw the organic molecule(s) which is(are) formed in this reaction. Do not include molecules like H$_2$O or HCl. Draw the specific configuration (R or S or both) at any chiral carbons within your product(s). If both configurations are formed in the product(s), both as separate molecules/products. (You have 2 chances until the answer will be given; you have already tried 0 times) Draw only one molecule in each drawing box.
