Stuck on the following question, anyone able to help?
'Squalene is a naturally occuring oil present in shark liver oil. A 0.100 mol sample of squalene reacted with 14.4 dm^3 of hydrogen, measured at r.t.p to form a saturated hydrocarbon C30H62.
(i) Calculate how many double bonds there are in each molecule of squalene.
(ii) Suggest the molecular formula of squalene.'

i) 0.1 mol reacted with 14.4 dm^3 of H2. 1 mole of hydrogen has a volume of 24 dm^3. So n=14.4/24= 0.6 mol of hydrogen
So each squalene reacts with 6 H2 molecules. So there must be 6 double bonds.Last edited by langlitz; 17-04-2016 at 21:51. -
