# Question 1. Calculate the m/z value for each of the molecular ions in the following compounds: to. ethane b. 1,2-dichloroethane c. p-bromophenol

&#12304;General guidance&#12305;The answer provided below has been developed in a clear step by step manner.Step1/21.)a) Ethane (C2H6)The molecular ion of ethane can be formed by removing one electron from the neutral molecule. This results in a positively charged ion with a mass equal to the molecular weight of the compound, which is 30.07 g/mol.The charge of the ion is +1, since one electron has been removed. Therefore, the m/z value of the ethane molecular ion is:$$\mathrm{\frac{{m}}{{z}}=\frac{{{30.07}{\left(\frac{{g}}{{{m}{o}{l}}}\right)}}}{{+{1}}}={30.07}}$$ExplanationThe m/z value (mass-to-charge ratio) of a molecular ion is the ratio of the mass of the ion to its charge. It is an important parameter in mass spectrometry, where it is used to identify and quantify compounds.Explanation:Please refer to solution in this step.Step2/ ... See the full answer
