Describe what a grignard reagent is, and what happens when a grignard reagent is added to carbonyl containing compounds.

For this assignment, I only need the introduction of this lab to be written with 3 sources . Please follow directions carefully below:

Briefly introduce the purpose of the experiment. Describe what a grignard reagent is, and what happens when a grignard reagent is added to carbonyl containing compounds Focus on the actual reagents and ester (methyl benzoate) that would be used in the synthesis of the intended product, triphenyl carbinol, a.k.a triphenyl methanol.

Here is a Youtube playlist ,

videos of someone performing the Grignard Synthesis of Triphenyl Methanol.
