Nucleophilic substitution of primary alkyl chlorides with sodium acetate is catalysed by sodium iodide. Discuss |
|
Answer» Solution :Primary lakyl chlorides `(R-CH_(2)-Cl)` are less reactive towards nucleophilic substitution as compared to primary alkyl IODIDES `(R-CH_(2)-I)` because C-I bond can cleave moreasily that `C-Cl` bond o accout of less bond dissociation enthalpy. Therefore, the catalyst sodium iodide CONVERTS alkyl chloride to alkyl iodide by finkelstin REACTION. the latter react with sodium acetate to form ester. `UNDERSET("ETHYL chloride")(CH_(3)-CH_(2)-)Cl+NaItounderset("Ethyl iodide")(CH_(3)-CH_(2)-)I+NaCl` `underset("Ethyl iodide")(CH_(3)-CH_(2)I+CH_(3)COONa)tounderset("Ethyl acetate")(CH_(3)COOC_(2)H_(5)+NaI` |
