Jacobsen Catalyst - the number of the electrons
« on: April 16, 2018, 04:42:01 PM »

How many electrons does the Cobalt have in that kind of compound? Are my calculations good?

Co = 9 electrons
2x N = 2x 2 electrons because of 2x covalent bondings
2x O = 2x 1 electron (im not sure)
So the right answer is 15?

Yes, the calculations are correct but your theoretical concept is wrong.
1). =N-Co bonds are not ordinary covalent bonds hereby, but they are “dative covalent bonds”; meaning that the bonding electrons are offered only from the N atom.
2). –O-Co bonds are ionic bonds because cobalt is in form of a phenolic salt, hereby.
