Chlorobenzene on mononitration with mixed acid gives mainly a mixture of two products.Write an arrow head equation of the reaction and explain why these two compounds are mainly formed.

Write the arrow-head equation for the following reactions: Aniline is refluxed with glacial acetic acid.

When two reactants A and B are mixed to give products C and D, the reactions quotient Q at the initial stages of the reaction

An alkylhalide (A), on reaction with Mg in dry ether followed by treatment with ethanol gave 2-methylbutane. Write all the possible structures of 'A'. Give arrow-head equation for the formation of 2-methly-butane from any one isomer of A

Two different organic compounds A and B have the same molecular formula of C_2H_6O .A reacts with metallic sodium,to produce hydrogen gas but B does not react with metallic sodium. Write structural formulas of the compounds,A and B. Write the balanced chemical equation of the reaction of A. with metallic,sodium.

Compound 'A' with molecular formula C_(4)H_(9)Br is treated with aq.KOH solution. The rate of this reaction depends upon the concentration of the compound 'A' only. When another optically active isomer 'B' of this compound was treated with aq. KOH solution, the rate of reaction was found to be dependent on concentration of compound and KOH both. (i) Write down the structural formula of both compounds 'A' and 'B'. (ii) Out of these two compounds, which one will be converted to the product with inverted configuration.

Name two gases which react with each other to form a solid. Give th equation and write down the name of the solid formed.

This question has statement I and Statement II . Of the four choices given after the statements, choose the one that best describes the two Statements. Statement-I:n-Propyl bromide on heating with alcoholic AgNO_2 gives 1 -nitropropane as the main product. Statement-II: AgNO_2 is an ionic compound and hence both oxygen and nitrogen electrons are available for reaction.

H_(2)O_(2) reacts with NaOH to give two types of salts - why? Write down the reactions.

An organic compound (A) with molecular formula C_(8)H_(8)O forms an orange-red precipitate with 2,4-DNP reagent and gives yellow precipitate on heating with iodine in the presence of sodium hydroxide. It neither reduces Tollens or Fehlings reagent, nor does it decolourise bromine water or Baeyerâs reagent. On drastic oxidation with chromic acid, it gives a carboxylic acid (B) having molecular formula C_(7)H_(6)O_(2) . Identify the compounds (A) and (B) and explain the reactions involved.
