(a) Give S_(N)2 and S_(N)1 mechanisms for the cleavage of ethers with Hl. (b) Why does S_(N)2 cleavage occur at a faster rate with Hl than with HCl? |
Answer» SOLUTION : (B) The transfer of `H^(+)` to ROR. in step 1 is greater with Hl, which is a stronger acid, than with HCl. FURTHERMORE, in step 2, `l^(-)`, being a BETTER nucleophile than `CL^(-)`, reacts at a faster rate. |
