An example of a sigma bonded organometallic compound is:

A

ruthenocene

B

Grignard's reagent

C

ferrocene

D

cobaltocene

Text Solution

Verified by Experts

The correct Answer is:
B
(b) The organometallic compounds having sigma bond between carbon and metal are sigma bonded organometallic. An example of a sigma bonded organometallic compound is Grignard's reagent.
`underset(sigma-"bond")ubrace(R-Mg-X)`
Whereas, ruthenocene, ferrocene and cobaltocene are not sigma bonded organometallic compound.
