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.

Br Brz CH3 CH3 H3C CH2CI2 H3C Br Electrophilic addition of bromine, Br2; to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl). In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions Br: :Br: .CH3 H3C H3C CH3 Br:
