Predict the tendency of undergoing possible mechanism for the athyl, isopropyl and t-butyl halides. (ii) Complete the following equations showing major product with reaction mechanism (S_(N)1,S_(N)2,E1,E2). |
Answer» Solution :When `S_(N)1` mechanism favoured it means that the activation ENERGY for this path is less than that for the `S_(N)2`. Practically, more stable the lon, the lower is the activation energy and more favoured will be the mechanism. As we KNOW, the order of stability of carbonium ion is `1^(@)LT2^(@)lt3^(@)`and hence the TENDENCY for the `S_(N)1` mechanism to operate will be `t-BuXgt" ios PROPYL "XgtEtX`. The tendency willbe reverse for the `S_(N)2` mechanism,
