Question
When the alkyl bromides (listed here) were subjected to hydrolysis in a mixture of ethanol and water (80% EtOH/20% H20) at 55°C, the rates of the reaction showed the
following order:
(CH3)3CB > CH3B > CH3CH2Br > (CH3)2CHBR
Provide an explanation for this order of reactivity.
Two different mechanisms are involved. (CH3)3CBr reacts by an
* mechanism and apparently this reaction takes place faster. The other three alkyl halides react by
* mechanism, and their reactions are slower because the
3. The reaction rates of CH3BR, CH3CH2Br, (CH3)2CHBR are affected by
an
* and thus their order of reactivity is CH3B > CH3CH2B > (CH3)2CHBR.
