An example of a sigma bonded organometallic compound is__________.
(a) Ruthenocene
(b) Grignard's reagent
(c) Ferrocene
(d) Cobaltocene
Answer : (b) Grignard's reagent
Explanation :
Organometallic compounds are defined as compounds containing a covalent bond between a carbon atom and a metal.
An example of a sigma bonded organometallic compound is Grignard's reagent (RMgX) in which R is hydrocarbons and X is halogens.
Whereas, ruthenocene, ferrocene and cobaltocene are not sigma bonded organometallic compound. But they are pi bonded compound with sandwich kind of overlapping.
b) Grignard's reagent
