or the compound:
carbon in the middle with 3 bonds
-double bond to oxygen
-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?
