M and M+2 peaks intensities are 100 and 31.8 which are in ratio of 3:1 .
This is possible if we have Cl as Cl has two isotopes of 35 amu and 37 amu in 3:1 ratio. Now
if we remove 35 amu from M peak of 112 we get 77 amu.
This 77 amu consists of C , H. Taking CH2 ( molar mass of 14) we get total CH2 units = ( 77 /14) = 6 rounded value.
Thus we had 6 carbons , now atomic mass of C and Cl combined = ( 12 x 6) amu + 35 amu = 107 amu
remaining mass comes from H =112amu - 107 amu = 5 amu
H has 1 amu atomic mass , hence total H = 5
Thus formula is C6H5Cl
