Toulene reacts with bromine and iron to give a mixture of three isomeric monobromo products, while with bromine in light it gives exclusively the fourth isomer. Justify the observation.

Propylbenzene reacts with bromine,in presence of light or heat to give:

Toluene reacts with bromine in the presence of light to give benzyl bromide while in presence of Fe Br_3 ,it gives p-bromotoluene give explanation for the above observation.

Phenol on treatment with Br_2 in CS_2 at low temperature gives two isomeric monobromo phenols 'X' and 'Y'. But phenol on treatment with bromine water giver a white precipitate 'Z'. Identify the products 'X','Y' and 'Z'.

When bromo benzene is monochlorinated, two Isomeric compounds A and B are obtained. Monobromination of A gives several isomeric products of molecular formula C_6 H_3 CI Br_2 , while monobromination of B yields only 2 isomers C and D . Compound C is identical with one of the compounds obtained from bromination of A , however D is totally different from any of the isomeric cómpounds obtained from the bromination of A , Give structures of A, B, C and D and also structures of four isomeric monobrominated products of A Support your answer with reasoning.

Bromine reacts with hot aqueous alkali to give bromide and bromate. What is the change that is brought about in the oxidation state of bromine to bromated (BrO_(3)) -?

Analyse the given reactions, give the major products. Justify your answer . Addition of chlorine to benzene in uv light.

While adding the raw materials into the Blast furnace for the extraction of iron, it is forgotten to mix lime stone with the change. a. Predict the result of this mistake b. Give reason for this result. c. Bessemer converter follows Blast furnace in a steel industry Justify.

Paragraph An organic compound A(C_(9)H_(6)O_(3)) does not react with aqueous solution of NaHCO_(3) as well as does not change the colour of litmus paper. Aon acid hydrolysis gives B(C_(9) H_(8)O_(4)) as major product whereas A on treatment with one equivalent of methanol in acidic medium gives C(C_(10)H_(10)O_(4)) as the major product (other minor isomer of C is also formed). B on heating with sodalime gives toluene. Answer the following questions based on the above information. The structure of product C is
