Propose an SN1 mechanism for the solvolysis of 3-bromo-2,3-dimethylpentane in ethanol.
SN1 mechanism :
The SN1 reaction is a substitution reaction in organic chemistry. "SN" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile.
Solvolysis of 3-bromo-2,3-dimethylpentane in ethanol:
In solvolysis of 3-bromo -2,3-dimethylpentane in ethanol it is the slow reaction initially the bromine atom is eliminated so forming carbo cation and this carbocation reacts with ethyl alcohol the lone pair of electrons present on the oxygen atom donates to the carbocation and thus forming the product by shifting and rearrangement of electrons here ethyl alcohol acts as base .
