Among the isomers of pentane (C5H12), write the one which on photochemical chlorination yields a single monochloride.
Among the isomer of pentane that will yield single monochloride on photochemical chlorination will be the one that only have one type of H- atom in the isomer of pentane. So, that type of pentane isomer is neopentane because in this, replacement of any ‘H’ leads to the formation of same product.
