Organometallic Compounds Notes Pdf Here BSC/MSC CEHEMISTRY

Introduction:- 

The branch of chemistry which deal with the study of organometallic compounds only transition metal involves in organometallic compounds.

Organometallic compound:- 

Those compound in which one or more atom directly attached to carbon atom called as organometallic compounds for example methyl lithium,dimethyl zinc,tetraethyl lead.

Biologically vitamin b12 are organometallic compound.

How to find compound is organometallic compound or not.

It can be defined by the electronegativity so we need to learn the electronenegatively table.If the electronegativity less than 2.5 it mean they have organometallic compound so so if electronegativity greater than 2.5 it mean they have not organometallic compound.

Mixed Organometallic Compound:- 

Those organometallic compound which make bond between metal and carbon as well as other covalent or ionic bond between metal and other carbon atom.

For example grignard reagent that is alkyl magnesium halide.

Key Points:- 

1. If metal atom is not directly attached with carbon atom then it is not a organometallic compound while they are called metallo organic compound.
2. Some complex which do not contain carbon metal bond but they are considered organometallic compound for example Wilkinson catalyst basically Wilkinson catalyst used in hydrogenation of alkene but reaction take place at one condition only carbon directly attached to the metal so this is organometallic compound.
