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 amino group of glycine methyl ester hydrochloride reacts with the double bond of acrylonitrile, it occurs the Michael reaction, then generates CNCH2CH2NHCH2CO2Me.
Formula: C6H5CH3
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
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.
Some additives I know of Ethyl methyl lead (octane booster and upper cylinder lube) Methyl Benzene (octane booster)
O-xylene is a benzene ring with two methyl groups in the ortho-positions. Methyl groups on a benzene ring act as o,p-directors, which means that they direct electrophiles to the carbon directly across or directly beside the existing methyl group. Friedel-crafts acylation creates the electrophile using a Lewis acid catalyst, however because there are two methyl groups side by side on o-xylene, the electrophilic addition is not as straightforward as described above. The two methyl groups direct the electrophile to different carbons, creating a mixture of products. As a result, there will be two products formed: One product will be a benzene ring with the electrophile and two methyl groups in a 1,2,3 orientation. The second product will be a benzene ring with the electrophile and two methyl groups in a 1,3,4 orientation (respectively). It is my understanding that the second product will be most predominantly formed, because it has the least steric hindrance (it is less crowded).
5g methyl orange dry dissolved with 100ml distilled water.
This group attached to benzene ring acts as the ortho-para directing group due to Hyperconjugation.
