An organic compound (A) (molecular formula, `C_4H_8O_2`) was hydrolysed with dilute `H_2SO_4` to give a carboxylic acid (B) and alcohol (C ). Oxidation of (C ) with chromic acid produced (B). Write possible structures of (A), (B) and (C ) and give their IUPAC name. Write the chemical equations involved in the process.

Write the balance chemical equations (vii) B(OH)_3 + H_2O rarr

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.

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.

Two moles of organic compound 'A' on teratment with a strong base give two compounds 'B' and 'C'. Compound 'B' on dehydrogenation with Cu gives 'A' while acidification of 'C' yield carboxylic acid 'D' with molecular formula of CH_2O_2 . Identify the compounds A, B, C and D. Write all chemical reactions involved.

Write the IUPAC name of the following: p-O_2N C_6H_4CH_2CI

Write the IUPAC name of the following: C_6H_5CH_2-CH=CH_2

Show that the points A(-1, 1), B(2, -2) and C(8, 4) are the vertices of a right angled triangle.
