Reaction of (R)-2-chloro-4-methylhexane with excess Nal in acetone gives racemic 2-iodo-4- methylhexane. What is the explanation that best describes this transformation? O an SN2 reaction has occurred with inversion of configuration O racemization followed by an SN2 attack O an SN1 reaction has occurred due to carbocation formation O an SN1 reaction has taken over resulting in inversion of configuration an SN1 reaction followed by an SN2 "backside" attack
