Concept explainers
(a)
Interpretation:
The velocity of electron required for an electron diffraction experiment if the wavelength is
Concept Introduction:
de Broglie established a relation for particles of matter that they also can behave as a wave and has a wavelength. The wavelength of the particle is inversely proportional to its mass. The smaller the mass, the larger its wavelength.
The expression given by the de Broglie is as follows:
Here,
The expression to calculate the root-mean-square speed of particle is as follows:
Here,

- A pdf file of your hand drawn, stepwise mechanisms for the reactions. For each reaction in the assignment, you must write each mechanism three times (there are 10 reactions, so 30 mechanisms). (A) do the work on a tablet and save as a pdf., it is expected to write each mechanism out and NOT copy and paste the mechanism after writing it just once. Everything should be drawn out stepwise and every bond that is formed and broken in the process of the reaction, and is expected to see all relevant lone pair electrons and curved arrows.
