-bond to Mn(CO)5
-bond to CH3 group
is the oxidation state of the metal +1?
d count 6?
total electron count 20?
coordination number 7?
D COUNT is electrons in the d orbital, and i think total is 20?
2 from CH3
CO each donate 2 (2x5=10)
carbonyl=2
total= 14 + d electrons= 20?
To determine the oxidation state of the metal in the compound, you can consider the oxidation states of the other elements and the overall charge of the compound. In this case, the compound contains a bond to Mn(CO)5, which means the oxidation state of the metal, manganese (Mn), can be determined by considering the oxidation state of carbon monoxide (CO).
The oxidation state of carbon in CO is -2, and since there are five CO ligands bonded to the metal, the total charge contributed by CO is -2 * 5 = -10. Therefore, the oxidation state of the metal must be +10 to balance out the charge. Therefore, the oxidation state of the metal Mn is +10, not +1.
Moving on to the "d count" and the total electron count, let's break it down:
- Carbon in the middle with 3 bonds: Carbon has 4 valence electrons and forms 3 bonds, so it is using three valence electrons.
- Double bond to oxygen: Oxygen has 6 valence electrons, and in a double bond, it shares 4 electrons (2 from each bonded atom), leaving 2 lone pairs.
- Bond to Mn(CO)5: Each CO ligand donates 2 electrons, and there are 5 CO ligands. Therefore, the contribution from Mn(CO)5 is 2 * 5 = 10 electrons.
- Bond to CH3 group: Each CH3 group has 4 valence electrons, and since there is one CH3 group, the contribution is 4 electrons.
Adding up these contributions:
3 electrons from carbon + 4 electrons from the double bond to oxygen + 10 electrons from Mn(CO)5 + 4 electrons from CH3 group = 21 electrons.
So, the total electron count in this compound is 21 electrons, not 20 as you mentioned.
Lastly, the coordination number refers to the number of ligands directly bonded to the central metal atom. In this compound, there are 3 ligands directly bonded to the central metal (oxygen, Mn(CO)5, CH3 group). Therefore, the coordination number is 3, not 7.
In summary:
- The oxidation state of the metal in the compound is +10, not +1.
- The "d count" is not mentioned and cannot be determined based on the given information.
- The total electron count in the compound is 21, not 20.
- The coordination number in the compound is 3, not 7.
