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

Acetic acid: Put in the molecular formula of the ions responsible for peaks at 45 and 43. Use the following order: C, H, O and include a '+' at the end. A formatting example for mass of 44 would be C2H4O+.

**Graph Explanation:**
- The graph displayed is a mass spectrum ranging from a mass-to-charge ratio (m/z) of 10 to 75.
- The y-axis represents the relative abundance of detected ions, labeled from 0 to 100.
- Notable peaks appear at m/z values of approximately 43, 45, and several others nearer to 60.

**Formulas:**
- C2H3O+ = 43
- COOH+ = 45

This information helps in identifying the possible fragmentation patterns of acetic acid in mass spectrometry.

Which one is the incorrect statement regarding mass spectrum? The structure likely contains a bromine atom if the (M+2)+ peak and (M)** are almost similar in heights The relative heights of (M)** peak and (M+1)** peak indicate the number of carbon atoms A signal at M-15 indicates the loss of a methyl group and a signal at M-29 indicates the loss of an ethyl group In case of alcohols, a signal at m/z = 18 is produced due to the loss of neutral H₂O molecule (Dehydration) The structure likely contains a chlorine atom if the (M+2)** peak is approximately one-third as tall as (M)*•
