NOTE: that the electron-withdrawing groups decrease the electron density around the proton nucleus and therefore the nucleus feels the external magnetic field more. Hence, it requires a larger frequency to attain resonance(downfield).
The oxygen wants to have a full valance shell and magnesium has just enough extra electrons to fill it.
Answer:
A dilute acid is when the concentration of water mixed in the acid is <em>higher</em> than the concentration of the acid itself. For example, 5% sulfuric acid is a dilute acid.
A concentrated acid is an acid that is in either <em>pure </em>form or has a <em>high </em>concentration.

Answer:
One way to synthesize alkenes is by dehydration of alcohols, a process in which alcohols undergo E1 or E2 mechanisms to lose water and form a double bond. The dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high tempera (sorry if this is wrong )
