Draw the structures and identify the relationship of the two products obtained when (R)-limonene is treated with excess hydrogen in the presence of a catalyst.

it would be a gas formation

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
