A' `(C_(6)H_(14)O)` is an organic compound which gives blood red colour with ceric ammonium nitrate. It gives iodoform test on treatment with `NaOH //i_(2)`, salt ofmonobasic acid 'B' is also formed during the reaction. Salt on acidification gives 2,3-dimethyl propanoic acid. What are 'A' and 'B', give their structural formulae ?

Silver salt of 2-methyl propanoic acid on reaction with bromine gives

Kolbe's electrolysis of sodium salt of 2, 2-dimethyl propanoic acid gives the following major product(s) at anode.

An organic compound gives hydrogen on reacting with sodium metal. It also gives iodoform test and forms an aldehyde of molecular formula C_(2)H_(4)O on oxidation with acidified dichromate. Name the compound and give the equation of these reactions.

An organic compound A(C_(6)H_(6)O) gives dark green colouration with ferric chloride. On treatment with CHCl_(3) and KOH , followed by acidification gives compound B. Compound B can also be obtained from compound C on reaction with pyridinium chlorochromate (PCC). Identify A, B and C

An organic compound (A) of molecular weight 135 on boiling with NaOH evolves a gas which gives white dense fumes on bringing a rod dipped in HCl near it. The alkaline solution thus obtained on acidification gives the precipitate of a compound (B) having molecular weight 136. Treatment of (A) with HNO_2 also yeilds (B), whereas its treatment with Br_2//KOH gives (C). compound (C) reacts with cold HNO_2 to give(D), which gives red colour with ceric ammonium nitrate. On the other hand(E) an isomer of (A) on boiling with dil HCl gives an acid (F), having molecular weight 136. On oxidation followed by heating, (F) gives an anhydride (G) which condenses with benzene in presence of AlCl_3 to give anthraquinone. Structural formula of compound (C) is

An organic compound 'A' has the molecular formula C_3H_6O , it undergoes iodoform test. Wheir saturated with dil. HCl it gives 'B' of molecular formula C_9H_(14)O . A and B respectively are

(i) How will you convert phenol to benzoic acid? (ii) An organic compound A having molecular formula, C_6H_6O gives a characteristic colour with aqueous FeCl_3 solution. A on treatment with CO_2 and NaOH at 400 K under pressure gives B which on acidification gives a compound C. The compound C reacts with acetyl chloride to give D which is a popular pain killer. Deduce the structure of A, B, C and D.
