Among the isomeric alkanes of molecular formula `C_(5)H_(12)`, identify the one that on photochemical chlorination yields.
(i) A single monochloride
(ii) Three isomeric monochlorides
(iii) Four isomeric monochlorides

Explanation

The possible isomers of alkane with molecular formula `C_(5)H_(12)` are :

In (i), there are three different hydrogen atoms and thus it will yeild three different products.

In (iii), all nine hydrogens are equivalent. So, it will yield only a sing monochloro product.

In (ii), there are four different hydrogens. So, it will yeild four different products.
