Modern techniques of chemistry

Organometallics are compounds that contain carbon-metal bonds that can be σ-bond or π-bond. Certain compounds e.g. metal alkoxides and metal carboxylates contain metallic and organic moieties but no direct carbon-metal bonds are present and these compounds are not considered as Organometallics. The present monograph showed the maximum contribution of Ca followed by Mg Fe and Zn in the local soils. The current average levels were also found to be many times lighter than those reported for other region of Pakistan. Dedicated to my Parents and respected Teachers.
