9.1 What is meant by molecular ion? What is the importance of identifying it to a chemist?

Answer 1

Answer #1

Molecular ion is the ion formed by the removal or addition of one or more electrons from a molecule.
If an electron added to the molecule than negative molecular ion forms.
While, if electron taken out from molecule than positive molecular ion forms.
Particularly in the mass spectroscopy a molecule to forms a positive molecular ion.
Molecular ion peak gives an idea about the molecular mass of the compounds.
For example, in the mass spectrum of pentane (C₅H₁₂), the molecular ion has an m/z value of 72 in mass spectrum.
