Year 12s: what will be the first way you research your future options? >>

why does Cl and m/z value of 106 and 108?

why does Cl and m/z value of 106 and 108 on the mass spectrum?

and why are 2 seperate peaks produce ( is it cuz of Cl35 and Cl37 )

I don't understand the first bit of your question, largely due to the fact that it makes no sense.

But yes there are two peaks due to the two isotopes of Chlorine.

CH3-CH2-CH2-CHCl-CH3 and various different isotopes would give m/z of 106 and 108 due to the two different iosotopes of Cl

15 + 14 + 14 + 13 + 35 + 15 = 106

15 + 14 + 14 + 13 + 37 + 15 = 108

The cl35 peak will be much higher (more intense) than the cl 37 peak. The two peaks will be in the ratio of there natural occourance, the more stable on being more intense (e.g. in the ratio 75% : 25%)
