which is tert-butyl bromide and is independent of the concentration of hydroxide ion. Rate $=k\left[\left(\mathrm{CH}_{3}\right)_{3} \mathrm{CBr}\right]$. Hence, the reaction occurs in two steps.
Two mechanisms are generally considered for the nucleophilic substitutions 1: the SN1 unimolecular substitution, which takes place in two steps: the first step corresponding to a slow and reversible dissociation to a cationic species. This mechanism usually leads to the racemization of an optically ...

The SN1 mechanism (Substitution, Nucleophilic, UNImolecular rate determining step) generally passes through two steps; first, a (slow, rate-determining) breaking of the C–LG bond on the substrate to form an intermediate carbocation, followed by (fast) addition of a nucleophile to the carbocation...
An SN1 reaction is a nucleophilic substitution reaction where the leaving nucleophile disassociates, and the attacking nucleophile binds the molecule in two separate steps, creating a stable carbon cation intermediate. An example of an SN1 reaction is the hydrolysis of tert-butyl bromide with water...
turned out to be scalable, useful in late-stage-functionalization and can yield highly interesting intermediates for allowing further chemistries to increase structural diversity in a quasi-exponential complexity increase, in just three steps: isocyanide synthesis, SN2 reaction, further aldehyde reaction. ...
i dont know the rest especially which steps go were in the mechanism becuase of two nucleophiles etc.??plus bonus question both are chiral as contain 4 diff groups on the stereogenic carbon centres. Logged azmanam Chemist Sr. Member Posts: 1416 Mole Snacks: +160/-24 Mediocrity is a ...
steps look like this. Because the nucleophile can attach either side of the carbocation, which adopts an sp2-hybridized orbital with a trigonal planar geometry, an equal amount of inversion and retention is seen, referred to as a racemic mixture. For reactivity using an Sn1 mechanism, tertiary...

double-inversion mechanism could be related with the already known roundabout mechanism. Since the first step of the double inversion is an abstraction-induced inversion, the reaction may result in an inverted reactant molecule as shown in the present study. Finding inverted reactants could be a ...
