This group attached to benzene ring acts as the ortho-para directing group due to Hyperconjugation.
methyl increases the electron density of the benzene ring and so the electron densities of the ortho para positions are high. hence it directs the newly attaching groups to ortho and para positions....
Tri-nitro toluene. Toluene is a benzene ring with a methyl group attached. The nitration of this to TNT occurs at the 2,4,6 positions.
The solubility difference between methyl alcohol (CH3OH) and benzene (C6H6) is related to the polar nature of methyl alcohol and the non polar nature of benzene. The OH group on methyl alcohol makes this a polar molecule and thus soluble in water. The lack of such a polar group in benzene makes it non polar, and thus insoluble in water.
The formula is C7H8.
The structural formula for p-xylene is C8H10. It consists of a benzene ring with a methyl group attached to the fourth carbon atom.
Benzene - a six carbon, six hydrogen [planar] ring - C6H6 - has no side-groups. Yet when any one single side-hydrogen is replaced with one Methyl (-CH3) Group, we have Toluene. Short Answer = one methyl group.

The formula is C7H8.
Formula: C6H5CH3
The structural formula for p-xylene is C8H10. It consists of a benzene ring with a methyl group attached to the fourth carbon atom.
since benzene has a very less boiling point , it will evaporate easily if the mixture is heated . Thus we can obtain the vapour and condense it to obtain solid benzene
because change happens
toulene+sulphuric acid = o-methyl benzene sulphonic acid + p-methyl benzene sulphonic acid. Since methly group is ortho and para directed group so it activates benzene ring for electrophilic substitution reaction.
Each is a completely different molecule. Toluene has a benzene ring with a methyl group attached, Ethanol is a 2 carbon chain with 5 hydrogen atoms and one OH group attached.
