The solution of (+)−2 - chloro −2 - phenylethane in toluene racemises slowly in the presence of small amounts of SbCl5 due to the formation of Carbocation.

Here's the step by step explanation:

1. SbCl5 is a strong Lewis acid. It accepts a pair of electrons from the chlorine atom in 2-chloro-2-phenylethane, forming a bond with it.

2. This results in the formation of a positively charged carbocation (a carbon atom with three bonds and a positive charge) and a chlorine ion.

3. The carbocation is unstable and can be attacked by other molecules or ions. In this case, it can be attacked by the chlorine ion or by toluene.

4. The attack can occur from either side of the carbocation, leading to the formation of both R and S enantiomers of the original molecule, thus causing racemisation.

5. Over time, an equal mixture of R and S enantiomers will be formed, which is a racemic mixture.
