Important of Grignard Reagent :
Grignard reactions are main due to their capacity to form carbon-carbon bonds. Grignard reagents are powerful bases and will react with protic compounds which makes them exceptionally valuable implement for organic synthesis.
Grignard reagents react fastly with acidic hydrogen atoms in molecules such as alcohols and water. When a Grignard reagent reacts with water, a proton return back halogen, and the product is an alkane. The Grignard reagent therefore provides a trace for transforming a haloalkane to an alkane in two steps.
When reacted with water,
RMgX + H2O -------> R-H + MgOH X
R ---- Alkyl Group
X --- Halogen

A vestigial structure is a feature of an organism's body that was once an adaptation shaped by natural selection, but which is no longer useful in their current environment. For example, some species of fish that live in completely dark caves have eyes, although their eyes cannot see and serve no function.
Answer:
An element is a pure substance that cannot be converted further into anything simpler than itself by physical or chemical process
