Which is more acidic -benzene or styrene

Benzene and styrene both are aromatic compound and have special chemical and industrial properties. 

 Here we are going to discuss their acid-base properties . 

Benzene have electron density cloud above and below the Internuclear axis. Due to this benzene acts as the nucleophile.    
 

     On treating with acid, pi bonds are get Delocalised and carbocation is formed. 

 Due to Delocalisation of pi bonds, carbocation Or conjugate  acid become stable . 

Similarly,in styrene ,benzylic carbocation  also become more stable due to delocalisation of pi electrons or bond. 

But carbocation formed in this case is  benzylic cation which is more stable than benzene cation . 

Extra stability in benzylic cation is due to greater resonating structures-

Now question is that , out of  benzene and styrene   , which one is more acidic? 

  Basic properties of_ of a molecule is determined by stability of cation intimidate.,  so more stable carbocation intermediate,  higher basicity of molecule. 

Here benzene is more acidic or less basic and styrene is more basic or  less acidic

Harmful effect of styrene 

Styrene Is Highly Flammable And Releases A Poisonous Gas When Burnt. If A Person Inhales Styrene, It Can Have An Adverse Impact On The Nervous System, Changes In Colour Vision, Tiredness, Feeling Drunk, Slowed Reaction Time, Concentration Problems, And Balance Problems
