(R)-3-Bromo-3-methylhexane loses its optical activity when dissolved in nitromethane, a highly polar but non-nucleophilic solvent. Explain this observation by providing a detailed mechanism.
Homework Answers
When
(R)-3-bromo-3-methylhexane is dissolved in highly polar nitro
methane solvent, it's undergo auto-ionisation to form a more stable
3° carbocation which is planar and sp2 hybridised. Due
to planarity of carbocation, nucleophile Br- ion can
approach from both sides with equal probability. As a result a
mixture of 1:1 (R) and (S) isomer will formed. Hence, loss of
optical activity observed.
