An alkyl compound `(C_5H_(11)X)` is an optically active compound. The compound was treated with metallic magnesium in ether and the product on treatment with ethanol produces 2-methyl-butane. Write all the reactions and find out the structure of the alkyl halide

An optically active amide (A)C_5H_(11)NO on acid hydrolysis gives an acid and NH_3 . When (A) is treated with bromide and alkali a compound is obtained which one treatment with nitrous acid gives an optically active alcohol and nitrogen. The alcohol gives positive iodoform test. What is the structure of A and show the reactions involved.

An organic compound contains A(C_7H_5N) on hydrolysis with strong aqueous acid gives another compound B which is a monobasic aromatic carboxylic acid. The compound B on treatment with ammonia gives a salt which on heating gives C. The compound C undergoes Hofmann's bromamide reaction to yield aniline. Name A, B and C and write the chemical reactions involved.

An organic compound X(C_2H_4O) , on oxi-dation, gives Y(C_2H_4O_2) . Compound (X) undergoes haloform reaction. On treatment with HCN, compound (X) produces Z which on hydrolysis, gives 2-Hydroxypropanoic acid. Write the equation for the reactions involved. What happens when X is treated with dilute NaOH?

An organic compound has the molecular formula C_5H_(10)O . The compound does not reduce Tollen's reagent but reacts with Brady's re-agent to give orange precipitate. On vigorous Oxidation, the molecule produces ethanoic acid and propanoic acid. The com-pound also gives iodoform test. Identify the compound and write equations for chemical reactions involved.

An aromatic compound (A) on treatment wth aqueous ammonia and heating forms a compound (B) which on heating with Br_2 and KOH froms a compound (c) of molecular formula C_6H_7N . Write the structures and IUPAC names of compounds.

A Chloro derivative (A) on treatment with Zn/Cu couple gives a hydrocarbon with five C-atoms when 'A' is dissolved in ether and treated with Sodium, 2,2,5,5 tetramethyl hexane is obtained. What is the original compound 'A'?

A compound X(C_2H_4O) on oxidation gives Y(C_2H_4O_2) . 'X' undergoes haloform reaction. On treatment with HCN, 'X' forms a product 'Z' which on hydrolysis given 2-Hydroxypropanoic acid.

An organic compound A on treatment with ethanol yields a carboxylic acid B and a neutral compound C.On hydrolysis, C produces B and another compound D. D on oxidation produces B, which on heating with Ca (OH)_2 gives E (C_3H_6O) E form 2,4 Dinitrophenyl hydrazone derivatives but does not show Fehling test.
