Concept Introduction:
Atoms with unstable nuclei are constantly changing as a result of the imbalance of energy within the nucleus. They constantly try to come to a stable state. This is possible when the nuclei of unstable isotopes spontaneously disintegrate, or transform, in a process known as radioactive decay.
Alpha emission = In an alpha emission the mass number reduces by 4 and the
Beta emission = Beta decay is a process in which a nuclei emits a particle which has 0 mass but charge of an electron from it. So the mass number remains the same however the atomic number reduces by 1 for the new nucleus.

- A mixture of C7H12O2, C9H9OCl, biphenyl and acetone was put together in a gas chromatography tube. Please decide from the GC resutls which correspond to the peak for C7,C9 and biphenyl and explain the reasoning based on GC results. Eliminate unnecessary peaks from Gas Chromatography results.arrow_forwardIs the molecule chiral, meso, or achiral? CI .CH3 H₂C CIarrow_forwardPLEASE HELP ! URGENT!arrow_forward
