Answer: 1. Grignard's reagent

Key idea: in a sigma-bonded organometallic compound, a metal-carbon sigma bond is present.

Grignard's reagent, R-Mg-X, has a direct Mg-C sigma bond. Ferrocene, cobaltocene and ruthenocene are sandwich compounds where the metal is bonded to the pi-electron cloud of cyclopentadienyl rings (pi-bonded).
