... From scandium, Sc, to cobalt, Co, there are just 7 transition metals, and thus the valence electron configuration must be 4s23d7. The 4s2 electrons are in 1 orbitals and thus paired. According to Hund's rule, into the set of 5 degenerate 3d orbitals first we place 5 unpaired electrons each one into ...

Williamson Ether Synthesis
... Ethers are prepared by SN2 reactions. Ethers can be prepared by the reaction of an alkoxide with a primary haloalkane or sulfonate ester under SN2 conditions. The parent alcohol of the alkoxide can be used as the solvent, however other polar solvents are often better, such as DMSO (dimethyl sulfoxid ...
