Answer 2

The molecular ion peak value of ethanol will be observed at the m/z value of 46.

• The chemical formula of ethanol is $C_2H_5OH$.
• When ethanol is bombarded with an electron the lone pair electron of the oxygen atom is removed from it and forms a molecular ion.
• The atomic mass of C is 12, oxygen is 16 and H is 1 grams.
• Hence the m/z value of the molecular ion peak of ethanol is 12×2+6×1+16=46.
• Hence the correct option is b.
