Explain why Grignard reagents should be prepared under

Grignard reagent should be prepared under anhydrous conditions, because it is very reactive. It reacts very quickly with any source of proton to give hydrocarbon. It reacts with water very quickly. Therefore, it is necessary to avoid moisture from the Grignard + H2O → RH + Mg(OH)X

Quality Protocol Aggregates from inert waste

Concrete: Scientific Principles

Concrete does not need to dry out in order to harden as commonly thought. The concrete (or specifically, the cement in it) needs moisture to hydrate and cure (harden). When concrete dries, it actually stops getting stronger. Concrete with too little water may be dry but is not fully reacted.
