Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

Identify the parent and propose a structure for the base peak in the mass
spectrum of butan-1-amine.

Relative abundance

Definition Definition Organic compounds with a nitrogen atom having a lone pair of electrons on it. Amines are derived from ammonia (NH 3 ), wherein hydrogen atoms are substituted by an aryl or alkyl group.

Expert Solution

Step 1

Mass spectrometry is used to detect the mass-to-charge ratio of the molecular ion. A plot of relative abundance vs m/z ratio is plotted to obtain the spectrum. A sample is bombarded with the fast-moving electrons to an ionized sample. After bombardment molecular ion is formed.

Step 2

From the spectrum, it is clear that the base peak is with m/z = 30 and the parent structure is at m/z = 73

A new compound has the empirical formula GaCl2. Thissurprises some chemists who, based on the position of gallium in the periodic table, expect a chloride of gallium to have the formula GaCl3 or possibly GaCl.

Potentially Useful Information Spectrochemical Series: | < Br < SCN¯ < Cl° < NO3¯ < F° < OH° < C2O4²¯ ~ H2O < NCS° < NH3 < en < PPH3 く A student has three test tubes containing a metal (M) nitrate solution M(NO3)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes.
