# You Are Given the Following Molecular Formulae of Some Hydrocarbons: C5h8; C7h14; C6h6; C5h10; C7h12; C6h12 Which Three Formulae Represent Open Chain Unsaturated Hydrocarbons Having Double Bonds? - Science

You are given the following molecular formulae of some hydrocarbons:
C5H8; C7H14; C6H6; C5H10; C7H12; C6H12

Which three formulae represent open chain unsaturated hydrocarbons having double bonds?

#### Solution

C7H14, C5H10 ,C6H12 are the molecular formulae for the open chain unsaturated hydrocarbons having double bonds, as they correspond to the general formula of alkenes, i.e. CnH2n,​ where n is the number of carbon atoms in its one molecule.

Is there an error in this question or solution?
