Question

An example of a sigma bonded organometallic compound is

• A. ruthenocene
• B. grignard's reagent
• C. ​​​​​​ferrocene
• D. cobaltocene

Answer 1

The correct option is B grignard's reagent

The organometallic compounds having sigma bond between carbon and metal are sigma bonded organomettalic. An example of a sigma bonded organometallic compound is Grignard's reagent.
$\underset{\sigma -bond}{\underset{}{R-Mg-x}}$
Whereas, ruthenocene, ferrocene and cobaltocene are not sigma bonded organometallic compound.
