If the mass spectrum of chlorobenzene shows a peak with an m/z value of 114, having an abundance of 15%, calculate the m/z value and approximate abundance of the molecular ion peak.

Explanation:

From the given information :

The molecular mass m/z of chlorobenzene = 112

Also the isotope of chlorine are:

 SInce isotopes are atoms with the same atomic number but different mass number .

With an abundance of 3:1

FOr a molecular ion peak; there is need for the presence of :;

As such the m/z value of M⁺ = 112 for a molecular ion peak

The approximate abundance at 112 for a molecular ion peak will be:

abundance of 15% × 3

= 15% × 3

= 45%
