haloalkene
with the help of polarity of c-x bond show that aryl halides are less reactive than alkyl halides
Laser action relies on a non-Boltzmann population inversion formed by the absorption of radiation and vibrational deactivation that forms a long lived excited electronic state. An excited state molecule can move to a lower energy state or return to the
