(a) The nucleophilic substitution of primary alkyl chlorides with sodium acetate is catalysed by sodium iodide. (b) p-Methoxybenzayl bromide reacts faster than p-nitrobenzyl bromide with ethanol to form a ether product. |

Answer» Solution :(a). In presence of NaI, alkyl chlorides form alkyl IODIDES which being more reactive CATALYSE the NUCLEOPHILIC substitution reaction. (b) p-Methoxybenzyl CATION is stabilized by the +R-effect of the methoxy group while p-nitrobenzyl cation is destabilized by the -R-effect of the `NO_(2)` group. |
