### Organic Chemistry Reaction Mechanisms: Worksheet#### Instructions:i) Predict the product(s) for the major mechanistic pathway(s). Show stereochemistry where applicable. If a racemate forms, draw one isomer and write "racemate."(This means that if there is an elimination, you only need to draw the major product of that. Or if there is a mixture of mechanism types, you would need the major product for each of the types.)ii) Write if the mechanism goes by \( S_{N}2 \), \( S_{N}1 \), E2, and/or E1.#### Reactions:- **Figure A:** A molecule has a Bromine (Br) atom attached to a secondary carbon. It is subjected to a reaction with Sodium Cyanide (NaCN). **Reaction Mechanism**: \( S_{N}2 \) (Typically the \( S_{N}2 \) mechanism occurs with a strong nucleophile like NaCN) **Expected Product**: - The Bromine (Br) will be substituted by the Cyanide (CN) group.- **Figure B:** A cyclic molecule with a Bromine (Br) atom attached to a secondary carbon is subjected to a reaction with Methanol (CH\(_3\)OH). **Reaction Mechanism**: \( S_{N}1 \) (Typically the \( S_{N}1 \) mechanism occurs with a weak nucleophile like CH\(_3\)OH and could proceed with carbocation formation). **Expected Product**: - The Bromine (Br) will be substituted by the Methoxy (OCH\(_3\)) group. ### Diagrams:- Both figures A and B show the structure of the organic molecules before the reaction. The Br (Bromine) atom has been placed on a secondary carbon and is represented in wedge notation to indicate stereochemistry.#### Note:* Ensure that in practical applications you consider the reaction conditions and solvents, as they can dramatically influence the pathway (SN2 vs SN1, E2 vs E1). ### Organic Chemistry Reactions Overview### Reaction Analysis#### Reaction B:The structure shown consists of a cycloalkane ring where one of the carbon atoms is bonded to a bromine atom (Br).**Reagent:** CH₃OH (Methanol)**Diagram description:**- A cycloalkane with the molecular formula including a bromine substituent.- An arrow indicating the reaction direction, labeled with CH₃OH.**Interpretation:**The given reaction suggests a substitution where methanol likely acts as a nucleophile, replacing the bromine atom on the cycloalkane.---#### Reaction C:The structure depicted is a straight-chain alkyl group terminated with a carbon-bromine (C-Br) bond.**Reagent:** (CH₃)₃OK (Potassium tert-butoxide)**Diagram description:**- A straight-chain carbon skeleton with a bromine substituent.- A reaction arrow labeled with (CH₃)₃OK indicating the direction of the reaction.**Interpretation:**This is likely an elimination reaction where potassium tert-butoxide induces the removal of the bromine atom, leading to the formation of an alkene due to the strong basic nature of the reagent.### SummaryThese reactions demonstrate common organic chemistry transformations — nucleophilic substitution and elimination — with specific reagents (methanol and potassium tert-butoxide) to achieve the desired chemical changes.
