Well, a carbonyl is an electrophilic centre.....

Explanation:

Well, a carbonyl is an electrophilic centre.....i.e. #R_1-stackrel(delta+)C(=O)R'#, the which is likely to react with a nucleophilic, carbanionic, Grignard reagent....#R^(-)""^(+)MgX#

#R^(-)""^(+)MgX+R_1-stackrel(delta+)C(=O)R'rarrR_1C(-O^(-))R'R#

On the other hand, an olefin, say ethylene, is a nucleophilic, electron-rich centre, the which is unlikely to react with another nucleophile. #alpha,beta-"unsaturated"# carbonyls can react in a Micheal addition fashion...
