Consider the solvolysis of -chloro-3-methylhexane in an excess of pure water. Predicting the stereocHaloalkanes and Haloarenes Chemistry Question

Question

Consider the solvolysis of $(S)-3$ -chloro-3-methylhexane in an excess of pure water. Predicting the stereochemical nature of the major synthesized product reveals it to be:

Answer: C

💡 Solution & Explanation

3-chloro-3-methylhexane is a tertiary alkyl halide. When solvolyzed in water (a polar protic solvent), it strictly undergoes an $S_N1$ mechanism. The chloride leaving group departs to form a planar $3^\circ$ carbocation. Water molecules subsequently attack this planar intermediate from both faces with roughly equal probability. As a result, the initially pure $(S)$ -enantiomer is converted into an equimolar racemic mixture of $(R)$ - and $(S)-3$ -methylhexan-3-ol.
