State a sentence discussing the external feel of the molecule specifically molecular polarity. Discuss which regions feel diverse charges that are the dipole or whether symmetry cancels out polarity but would leave the substance mimicking a negative or positive ion in a solution such as water, or whether it's non-polar as well as wholly neutral and would not mix well with polar solvents such as water.AsF6 SCl6CH2Cl2
Derive ( in Cartesian coordinates) the quantum mechanical operators for the three components of angular momentum starting from the classical definition of angular momentum, l = r × p. Show that any two of the components do not mutually commute, an..
