Question

I  need explanation .The following spectrum is of a haloalkane. Identify the halogen and suggest a possible alkyl group. Fully explain your answer, making reference to both molecular and fragment ions.
Note that the two peaks with highest m/z values occur at 108 and 110, with the peak at m/z 110 having an intensity of approximately 95% of that at m/z 108.

and the answer is : i need explanation 

It is the spectrum of ethyl bromide
Formula: C2H5Br
Molecular weight: 108.965 g/mol
Peaks with an m/z of 108 and 110 correspond to [C2H579Br]+ and [C2H581Br]+
