Structural isomerism

Consider the isomers of hydrocarbon with molecular formula $\ce{C5H10}$. These isomers do not decolourise $\ce{KMnO4}$ solution. These isomers are subjected to chlorination with chlorine in presence of light to give monochloro compounds. The total number of monochloro compounds (structural isomers only) formed is ________.

Given below are two statements:

Statement I: 2,6-diethylcyclohexanone and 6-methyl-2-n-propylcyclohexanone are metamers.
