what type of organic reaction is the following:
chloroethane + naoch2 ch3 →
elimination
combustion
substitution
addition

Explanation:

• Elimination reaction: In an elimination reaction, atoms or groups are removed from a molecule. Here, it's not the case as we are looking at substitution.
• Combustion reaction: Combustion reactions involve a substance reacting with oxygen to produce carbon dioxide and water (for organic compounds). This reaction is not a combustion.
• Substitution reaction: In a substitution reaction, one atom or group is replaced by another. In the reaction of chloroethane (\(CH_3CH_2Cl\)) with \(NaOCH_2CH_3\), the \(Cl\) atom in chloroethane is replaced by the \(OCH_2CH_3\) group. The general form of substitution reaction for alkyl halides is \(R - X+Nu^-\to R - Nu+X^-\), where \(R - X\) is the alkyl halide (here \(CH_3CH_2Cl\)), \(Nu^-\) is the nucleophile (here \(OCH_2CH_3^-\) from \(NaOCH_2CH_3\)), \(R - Nu\) is the substituted product (\(CH_3CH_2OCH_2CH_3\)) and \(X^-\) is the leaving group (\(Cl^-\)).
• Addition reaction: Addition reactions involve adding atoms or groups to a multiple - bonded molecule (like alkenes or alkynes). This reaction is not an addition.

Answer:

Substitution
