An alkane A on ozobolysis yields acetone and an aldeyde. 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.

When an aldehyde with no alpha -hydrogen react with concentrated aqueous NaOH, half the aldehyde is converted ot carboxylic acid salt and other half is converted to an alcoho. In other words, half the reaction is oxidized and other half is reduced. This reaction is known as Cannizzaro reaction Find out the products of following reaction : X and Y are :
