What is the molecular formula of a hydrocarbon with m+ = 78?
fiasKO [112]

A molecular formula represents the exact number of atoms present for each element in the compound.  

For carbon atom: \frac{78}{12} = 6\frac{6}{12} ( as molar mass of carbon is 12 g/mol)

Now, 6 carbon atoms are present and rest are hydrogen atoms i.e. 6

Thus, formula becomes C_{6}H_{6} ( C_{x}H_{y})

Now, check for unsaturation:

Degree of unsaturation  = \frac{2x+2-y}{2}

Substitute the value of x and y,

Degree of unsaturation  = \frac{2(6)+2-6}{2}

= \frac{12-4}{2}

= 4 implies one ring and three double bonds.

Thus, formula comes out to be C_{6}H_{6} i.e. benzene ring.
