    Question on structures in Organic Chemistry!!
    3.52 mg of compound "A" reacts with red Phosphorous and Bromine to gine compound "B". Compound "B" on reaction with KCN fives "C" which on hydolysis gives "D". "D" is optically inactive. "D" on mild heating gives "E" & "F". "E" on further heating in presence of Soda Lime gived "F" & "G". Both "F" & "G" are gases and only "F" is soluble in NaOH. "F" evolved from "E" is passed through excess of NaOH solution (12 ml of 0.01 M) and resulting solution requires 8 ml of 0.01 M HCl to reach end point by using phenolpthalein as indicator. After attainment of equivalence point further 4 ml of 0.01 M HCl was added. Find out pH of resilting solution if Ka1 and Ka2 for carbonic acid are 4.45 X 10 (raise to power of -7) and 4.69 X 10 (raise to the power of -11) respectively.
    In another experiment compound "E" reacts with SOCl2 to give "H", which on reaction with Hydrogen, palladium in presence of Barium Sulphate gives "I". "I" in presence of dil. NaOH gives "J" which does not undergo easy dehydration on heating.

    Find out the structure of A,B,C,D,E,F,G,H,I,J.
