Questions/Answers
Why is the chemistry of thecarbon atom in organometalliccompounds different than inorganic compounds?
( Hint: Compare the polarity of the non-hydrogen to carbon bonds to the ones in a compound like tetraethyl lead, (CH3CH2)4Pb. ) Thanks!
In an organic compound, carbon is typically bonded to other atoms of equal or greater electronegativity (C, H, N, P, O, S, F, Cl, Br, I) and as a result of this, it is positively polarized and electrophilic. In an organometallic compound, carbon is bonded to atoms with lower electronegativity, such as Li, Mg, Zn, Cd, etc. so it is negatively polarized and nucleophilic. (Lead is no exception.)
Name this organometalliccompound [PdCl2(PPh3)2]?
This is not an organometallic compound, it is a coordination compound with the name dichlorobis(triphenylphosphine )palladium (II). good luck.
Are the carbon-metal bonds inthese organometallic compoundsnonpolar covalent, polarcovalent or ionic?
a.Tetraethyllead b.Methylmagnesium chloride c.Dimethylmercury Can you also show the direction of its polarity please? Thnx!!!
All of these carbon-metal bonds are polar covalent because the difference in electronegativities is between 0.5 and 1.9 for all. In each case, carbon is the more electronegative element so it has the partial negative charge. To show the polarity directions: a.Write delta^- over CH2 of the ethyl group; delta^+ over the lead. b.Write delta^- over CH3; delta^+ over the magnesium. c.Write delta^- over the CH3; delta^+ over the mercury.
