Interpretation Introduction

Interpretation:

Collisionally activated dissociation has to be defined and at what points in a mass spectrometer it occurs has to be indicated.

Concept introduction:

Collisionally activated dissociation:

  • Collisionally activated dissociation (CAD) is also said to be as collision-induced dissociation (CID).
  • Which is used in mass spectrometry method to induce fragmentation of molecular ions in the phase of gas.
  • Usually molecular ions are gets accelerate by electrical potential to high kinetic energy and which leads to colloid with neutral molecules.
  • This method is used to achieve the partial or complete structural determination.

Can the target compound at right be efficiently synthesized in good yield from the unsubstituted benzene at left? starting material target If so, draw a synthesis below. If no synthesis using reagents ALEKS recognizes is possible, check the box under the drawing area. Be sure you follow the standard ALEKS rules for submitting syntheses. + More...
