(i) Draw all possible stereo isomers of a complex Ca[Co(NH_(3))Cl(Ox)_(2)] (ii) What is Bragg'sequation ? |
Answer» Solution :(i) Possible STEREO isomers of a complex `Ca[Co(NH_(3))Cl(Ox)_(2)]`  1. X-raydiffraction analysis is the most POWERFUL tool for the determination of crystal structure. 2. The interplanardistance (d) between two successive planes of atoms can be calculated using the following equation form the X-ray diffraction data `2d sin theta=n lambda`. The equation is known as Bragg.s equation Where `lambda` = WAVELENGTH of X-ray,d = Interplanardistance `theta` = The angle of diffractionn = order of reflection By knowing the values of `theta,lambda` and n. we can CALCULATE the value of d `d=(n lambda)/(2sin theta)` Using these values, the edge of the unit cell can be calculated. |
