State True/False A reaction in which hydrogen of an alkane is replaced by a halogen is known as Halogenation reaction

An alkene A on ozonolysis yields acetone and an aldehyde. The aldehyde is easily oxidised to an acid B. When B is treated with bromine in presence of yields a compound C which on hydrolysis gives a hydroxyle acid D. This acid can also be obatined from acetone by the reaction with hydrogen cyanide followed by hydrolysis. Identify the compounds A, B C and D.

Identify A to E. Pyrolusite on heating with KOH in the presence of air gives a dark green compound (A). The solution of (A) on treatment with H_2SO_4 gives a purple coloured compound (B) , which gives the following reactions: (a). KI on reaction with alkaline solution of (B) changes into a compound (C). (b). The colour of the compoud (B) disappears on treatment with the acidic solution of FeSO_4 . (c). With conc. H_2SO_4 compound (B) gives (D) which can compose to yield (E) and oxygen.

Carboxylic acids having at least one alpha -hydrogen react with Cl_(2)" or "Br_(2) in the presnence of red phosphorus to give alpha -halo acids. The reaction is known as H.V.Z. reaction.
