Benzene is produced as a side product when water react with phenyl magnesium bromide during Grignard reactions.
<h3>What is Grignard Reaction ? </h3>The Grignard reaction involves an R-Mg-X, a carbon chain bound to a magnesium halide, used to form alcohols by attacking carbonyls such as in aldehydes or ketones.
Here R act as a nucleophile and Mg-X act as a electrophile. Instead of attacking carbonyl, which is present in the reaction, the benzene ring will attack water molecules present around, grabbing a H⁺ and pushing away MgBr .
The required reaction is :
PhMgBr + H₂O → Ph-H + MgBrOH
Thus from the above conclusion we can say that it is always advised to use dry Grignard to avoid this reaction.

Explanation:
In nitrate ion that is ,have negative charge on overall ion. Negative charge on the one oxygen atom is de-localized to other oxygen atoms present in the molecule of a nitrate ion. Due to this resonance nitrate ions get stabilized.
For resonance structures for the nitrate ion, refer to image attached.
