LUCKY_DIMON [66]
Volume of a rectangular block= 2.30x4.01x1.82=16.78cm3
Mass of the rectangular block= 25.71 g 
Density of the block will be = 25.71/16.78=1.53 g/cm3
So the

Alex_Xolod [135]

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.
