Red Phosphorous

Red and white Phosphorous will differ but not in

In the presence of a small amount of red phosphorous, aliphatic carboxylic acids react with chlorine or bromine to yield a compound in which alpha -hydrogen has been replaced by halogen. This reaction is known as

A linear chain compound 'A' (C_(5)H_(10)O_(2)) gives brisk effervescence of CO_(2) when treated with saturated aqueous NaHCO_(3) solution. It reacts with chlorine gas in the presence of catalytic amount of red phosphorous to give compound 'B' . Identify compound 'A' and 'B' . Identify the chiral isomer of compound 'A'/

Compound (A) C_(5)H_(10)O_(5) give a tetra-acetate with Ac_(2)O and oxidation of (A) with Br_(2)-H_(2)O gives an acid, C_(5)H_(10)O_(6) Reduction of (A) wilh HI and red phosphorous gives 2-methyl butane. What is the structure of (A)?

(a) A tetratomic molecule (A) on reaction with nitrogen (I) oxide, produces two substances (B) and ( C) is a dehydrating agent while substance ( C) is a diatomic gas which shows almost inert behaviour. Identify (A),(B) and ( C) . (b) Why red phosphorous is denser and chemically less reactive than while phosphorous ? ( c) Why nitrous oxide supports combustion better than air ?

An organic compound 'A' having molecular formula C_2H_6O evolves hydrogen gas on treatment with sodium metal and on treatment with red phosphorous and iodind gives compound 'B'. The compound 'B' on treatment with, alcoholic KNC and on subsequent reduction gives compound 'C'. The compound 'C' on treatment with nitrous acid evolves nitrogen gas. Write the balanced chemical equations for all the reactions involved and identify thecompound 'A' 'B' and 'C'.
