Boiling point 111° C. Flammability High flammable. Vapor pressure 4.89kPa. ph value 7. f Properties of methyl benzene. It is immiscible with water. It burns in oxygen. C6H5CH3 + 9O2 → 7CO2 + 4H2O.
Chlorobenzene to benzene. As mentioned earlier, bromobenzene and chlorobenzene have similar reaction with magnesium in ether medium. First, chlorobenzene reacts with magnesium in ether medium. It gives phenyl magnesium chloride which has grignard reagent characteristics. Then add water to phenyl magnesium bromide to hydrolyze the grignard reagent.
Methyl benzene can be prepared by reacting benzene with bromo-methane in the presence ofa)Anhydrous AlCl3b)Br2/CCl4c)Ni/H2, 70oCd)Dil. H2SO4Correct answer is option ''A''. Can …
3. Sulfonation of Benzene. Sulfonation of benzene includes an electrophilic substitution reaction that occurs between benzene and sulfuric acid. There are two equivalent ways of sulfonating benzene: The first way involves heating of benzene under reflux of concentrated fuming sulfuric acid for several hours at 40°C.
Step 1: Nitric acid takes a proton from sulphuric acid before dissociating to generate the nitronium ion. Step 2: In the procedure, the nitronium ion works as an electrophile, reacting with benzene to generate the arenium ion. Step 3: The arenium ion then loses its proton to Lewis base, resulting in the formation of nitrobenzene.
In this video, we will learn about addition and substitution reactions of benzene. We will learn how to predict what products are formed in these reactions. Benzene is an organic hydrocarbon molecule with molecular formula C6H6. It is colorless to slightly light yellow and is a liquid at room temperature. It is highly flammable, and it is a

NBS (N-bromosuccinimide) is the most commonly used reagent to produce low concentrations of bromine. When suspended in tetrachloride (CCl 4 ), NBS reacts with trace amounts of HBr to produce a low enough concentration of bromine to facilitate the benzylic bromination reaction via a radical process. Exercises Questions Q16.9.1 Predict the products.
Correct option is D) Chlorobenzene reacted with the very strong base sodium amide NaNH 2 at low temperature −33 oC in liquid ammonia to give aniline (aminobenzene). NH 2− replaces Cl …

26/8/2022· Methylbenzene is more reactive than benzene because of the tendency of the methyl group to "push" electrons towards the ring. The effect of this greater reactivity is that methylbenzene will react with fuming sulfuric acid at 0°C, and with concentrated sulfuric acid if they are heated under reflux for about 5 minutes.
