Molecular formula tells that how many atoms of each element are present in a compound
Empirical formula tell you the simplest or most reduced ratio of elements in a compound.
If we complete the valency of the atoms then the structure is as follows whose molecular formula is C8H16N2
and empirical formula is C4H8N (by dividing 8,16,2 by 2) we need to get the smallest number so that it cannot be reduced further.
If it is needed as it is without completing valency, then it is
with molecular formula: C8H6N2
Emperical formula: C4H3N (dividing molecular formual by 2)
