The empirical formula for benzene is CH.
Benzene has a molecular formula of C6H6. The empirical formula represents the simplest whole-number ratio of atoms in a compound. To determine the empirical formula, we find the greatest common divisor (GCD) of the subscripts in the molecular formula and divide each subscript by the GCD.
In the case of benzene (C6H6), the GCD of 6 and 6 is 6. Dividing both subscripts by 6 gives us:
C6/6H6/6 = CH
Therefore, the empirical formula for benzene is CH. This means that for every carbon atom in benzene, there is one hydrogen atom, in its simplest ratio.
