Identify the functional groups present in the molecule. The given structure is a cyclohexane ring with two hydroxyl groups (OH) attached, indicating it is a diol.
Consider the reaction with SOCl₂. This reagent typically converts alcohols to alkyl chlorides. Each hydroxyl group can be replaced by a chlorine atom.
Consider the reaction with PBr₃. This reagent is used to convert alcohols to alkyl bromides. Each hydroxyl group can be replaced by a bromine atom.
Consider the reaction with SOCl₂ and NEt₃. NEt₃ is a base that can facilitate the conversion of alcohols to alkyl chlorides by deprotonating the alcohol, making the reaction more efficient.
Consider the reaction with TsCl and Et₃N followed by NaCN. TsCl converts alcohols to tosylates, which are good leaving groups. NaCN can then perform a nucleophilic substitution, replacing the tosylate group with a cyano group (CN).

Functional Group Transformations

Recognizing how different functional groups react under various conditions is vital for predicting products. For instance, alcohols can be converted to alkyl halides or undergo oxidation to form carbonyl compounds. This knowledge enables the identification of potential products based on the starting materials and the reagents used.
