Manufacturers require far greater amounts of isoprene than can be obtained from natural sources.
Suggest how this synthetic intermediate is obtained industrially in bulk quantities. Name one catalyst which can speed up a similar dehydration in the laboratory. The molar mass of a monomeric unit in natural rubber is 68 g mol- . If the molar mass of a sample of natural rubber is 1.02 x 10 kg mol- , calculate the value of 'n' in the molecular formula. In sharp contrast to its r le in the upper atmosphere, protecting the biosphere from harmful u.v. radiation, ozone causes the destruction of a diverse range of synthetic and naturally occurring molecules.
