Assume that 2-chloropropane reacts with CN− in an SN2 reaction. Use the JSME editor () to draw the structure of the substitution product of the reaction. The guide on how to draw your structure can be found here Important Note: When drawing the structures in the JME editor please adhere to the following formats: 1. If the nucleophile is OH−, DO NOT manually add the "H" to the final product 2. If the nucleophile is CN−, be sure to include the appropriate bonding between the C and N in the final product

Reactions are impacted by various factors that depend on the mechanism of the reaction.Some of the variables for substitution reactions are: • strength of the nucleophile • concentration of the nucleophile • leaving group ability (i.e., is it a “bad” or a “good” leaving group?In an SN2 reaction, the nucleophile forces the leaving group to leave. (This is the rate-determining step of the reaction.)In an SN1 reaction, the nucleophile does not attack until the leaving group has left. (When the leaving group leaves, this is the rate-determining step of the reaction.) Based on the information provided in this question, which factors would favor an SN2 reaction? a strong nucleophile a good leaving group a high concentration of nucleophile
