Question

Upon analysis, a hydrocarbon was found to contain82.8% carbon and 17.2%hydrogen. Calculate the empirical formula. 1.00g of hydrocarbon (as a gas) had a volume of 420mL at 1atm pressure and at 298K. Calculate the molecular weight and hence the molecular formula. Draw all possible structures for this compound and name them.

 

Answer 1

Molecular weight =69.4g

Molecular formula =C4H8
