Alkyl HalidesStereochemistry of SN1 Reaction21Choose the best answerPartial racemization in an SN₁ reaction occurs because:AThe nucleophile attacks only from the leaving-group side.BThe carbocation is tetrahedral.CThe nucleophile can attack both faces of the planar carbocation, often with greater attack from the less hindered opposite face.DThe nucleophile cannot approach the carbocation.
