Q7 / 90 · JEE Main 2013 (07 Apr) · Chemistry
A solution of in toluene racemises slowly in the presence of a small amount of SbCl5, due to the formation of :
- Correct answerACarbocation
- BFree radical
- CCarbanion
- DCarbene
Solution
(-) - 1 - chloro-1-phenylethane is:
.

With SbCl5 carbocation is formed. As the carbocation is planar, can again attack from both sides giving racemic mixture. (d, l mixture formed)
Hence, the correct answer is option: 'A'.
