Why can classical (Werner) octaedral complexes with no pi-bonding have between 12-22 valence electrons, whereas octahedral complexes with pi-bonding must have 18 electrons?
Q. What is speed of light wave? Ans. Light is just one type of wave. Like all waves it can be characterized by frequency, wavelength and amplitude. Similarly, light waves ca
Chromium has the electronic configuration 4s 1 3d 5 rather than4s 2 , 3d 4 because: (1) 4s and 3d have the same energy (2) 4s has a higher energy than 3d (3)4s 1 is
Explain Newman projections The systematic name for "pullane" is 1,1-di-tert-butyl-2,4-diethylcyclopentane. Hence, structures B and C are Newman projections of the same compo
