Given :-
m/z = 82
Formula of M/13 rule
M/13 = n + r /13
The rule of 13 states that the formula of a compound is a multiple n of 13 (the molar mass of CH) plus a remainder r.
Explanation:
The formula is used in interpreting mass spectra.
Molecular formula=CnHn+r
by formula
there for n = 6 and r = 4
C6 H6+4
C6H10
