Among the isomeric alkanes of molecular formula C_5H_12 identify the one that on photochemical chlorination yields. A single monochloride.

Write IUPAC names of the following compounds: C_6H_5-O-C_2H_5

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 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 A (C_3H_6O) is resistant to oxidation but forms compound B (C_3H_8O) on reduction. 'B' reacts with HBr to form the compound 'C'. C with Mg forms Grignard reagent 'D' which reacts with 'A' to forms a product which on hydrolysis gives. E. Identify A to E

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 unknown aldehyde 'A' on reacting with alkali gives a beta hydroxy aldehyde, which losses water to form an unsaturated aldehyde, but-2-enal. Another aldehyde 'B' undergoes disproportionation reaction in the presence of conc alkali to form products 'C' and 'D'. 'C' is an aryl alcohol with formula C_7H_8O : Identify A and B.
