Question

What does the M+ peak tell you about a molecule?

A) It indicates the molecular weight of the molecule.
B) It provides information about the molecule's structure.
C) It reveals the molecule's color and appearance.
D) It signifies the molecule's reactivity.

Answer 1

The M+ peak in mass spectrometry represents the molecule's molecular mass, which is crucial for inferring its molecular formula. The peak on its own doesn't provide detailed structural information nor details about color, appearance, or reactivity.

Step-by-step explanation:

The M+ peak in mass spectrometry tells us about the molecular weight of the molecule. Mass spectrometry is an analytical technique that allows us to determine the mass of molecules and fragments. The M+ peak represents the molecular ion, which is formed when a molecule loses one electron.

This peak corresponds to the molecular weight of the molecule. The M+ peak in mass spectrometry represents the molecule's molecular mass, which is crucial for inferring its molecular formula. The peak on its own doesn't provide detailed structural information, nor details about color, appearance, or reactivity.
