An example of a sigma bonded organometallic compound is (NEET 2017)
A.Grignard’s reagent (b) ferrocene
C.cobaltocene
D.ruthenocene
Explanation
An example of a sigma bonded organometallic compound is Grignard’s reagent. Grignard's reagent is represented by R−MgX. An example of this is methyl magnesium iodide. A sigma bond is present between C and Mg atom. Therefore, the correct option is (a). 43. Pick out the correct statement with respect to [Mn(CN)6] 3–. (NEET 2017) (a) It is sp3d2 hybridized and tetrahedral. (b) It is d2sp3 hybridized and octahedral. (c) It is dsp2 hybridized and square planar. (d) It is sp3d2 hybridized and octahedral. 31 COORDINATION COMPOUNDS In this complex [Mn(CN)6]
