Answer
The explanation is given below.
Work Step by Step
As we can see, the twelve hydrogen atoms of cyclohexene are on equivalent$2^{\circ}$ carbon atoms. Replacement of any of these hydrogen atoms will lead to the same product, chlorocyclohexane. But in hexane, the hydrogen atoms are on three different carbon atoms - C1/C6, C2/C5, C3/C4. So, chlorination of hexane gives a mixture of all possible isomers 1-, 2-, and 3-chlorohexane.
