A solution of ( - ) 1 - chloro - 1 - phenylethane in toluene racemises slowly in the presence of a small amount of SbCl 5 , due to the formation of :
Options
- ACarbocation
- BFree radical
- CCarbanion
- DCarbene
Correct answer
A. Carbocation
Step-by-step solution
(-) - 1 - chloro-1-phenylethane is: . With SbCl 5 carbocation is formed. As the carbocation is planar, Cl ⊖ can again attack from both sides giving racemic mixture. (d, l mixture formed)
