Classify each reaction as a substitution, an elimination, or neither. Identify the leaving group in each reaction, and the nucleophile in substitutions.
a. 
검증된 단계별 안내1
Identify the type of reaction: The reaction involves the replacement of an iodine atom with an ethoxy group (OCH2CH3), indicating a substitution reaction.
Determine the leaving group: In the given reaction, the iodine atom (I) is the leaving group as it is replaced by the ethoxy group.
Identify the nucleophile: The nucleophile in this reaction is the ethoxide ion (OCH2CH3-) from the sodium ethoxide (Na+ -OCH2CH3).
Analyze the reaction mechanism: This is likely an SN2 reaction because it involves a primary alkyl halide and a strong nucleophile, leading to a direct displacement of the leaving group.
Consider the reaction conditions: The presence of a strong base and a primary substrate supports the SN2 mechanism, where the nucleophile attacks the carbon atom bonded to the leaving group, resulting in the substitution.

Substitution Reaction
A substitution reaction involves the replacement of an atom or a group of atoms in a molecule with another atom or group. In the given reaction, the iodide ion (I-) is replaced by the ethoxy group (OCH2CH3) from sodium ethoxide (Na+ -OCH2CH3), indicating a nucleophilic substitution reaction.

Recognizing Substitution Reactions.
Leaving Group
A leaving group is an atom or group that can depart with an electron pair, forming a stable species after the departure. In the reaction, the iodide ion (I-) acts as the leaving group, as it detaches from the cyclohexane ring to form sodium iodide (NaI), facilitating the substitution process.

Nucleophile
A nucleophile is a chemical species that donates an electron pair to form a chemical bond in a reaction. In this reaction, the ethoxide ion (OCH2CH3-) from sodium ethoxide acts as the nucleophile, attacking the carbon atom bonded to the iodide ion, leading to the formation of the new ether linkage in the product.
