Red Phosphorous

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 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'/

(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 ?

White Phosphorous

The reducing strength of oxyacid of the Phosphorous depends on
