Long Answer TypeIn 'x' mL 0.3 N HCl, the addition of 200 mL distilled water or addition of 100 mL 0.1 N NaOH, gives the same final acid strength. Determine 'x'.
Compound A treated with NaNH2 followed by CH3CH2Br gave compound B. Partial hydrogenation of compound B produced compound C, which on ozonolysis gave a carbonyl compound D, (C2H5O). Compound D did not respond to the iodoform test with I2/KI and NaOH. Find out the structures of A, B, C and D.
The bacterial growth follows the rate law, dN/dt = kN where k is a constant and 'N' is the number of bacteria cell at any time. If the population of bacteria (number of cell) is doubled in 5 min find the time in which the population will be eight times of the initial one?
An organic compound with molecular formula C9H10O forms 2, 4-DNP derivative, reduces Tollen's reagent and undergoes Cannizaro reaction. On vigorous oxidation, it gives a dicarboxylic acid which is used in the preparation of terylene. Identify the organic compound.
Deep blue CuSO4.5H2O is converted to a bluish-white salt at 100oC. At 250oC and 750oC it is then transformed to white powder and black material respectively. Identify the salts.
The Deep blue CuSO4.5H2O is blue vitriol. In its structure, one molecule of water is hydrogen-bonded from 4 sides and thus is released with more difficulty than the rest four water molecules.
