An organic compound neither reacts with neutral ferric chloride solution nor with fehling solution.
it however, reacts with Grignard reagent and gives positive iodoform test. The compound is :

An organic compound 'X' showing the following solubility profile is :

An organic compound 'A' is oxidizod with Na2O2 followed by boiling with HNO3. The resultant solution is
then treated with ammonium molybdate to yield a yellow precipitate.

In a complexometric titration of metal ion with ligand
M(Metal ion) + L(Ligand) \(\to\) C(Complex) end point is estimated spectrophoto - metrically (through light absorption). If 'M' and 'C' do not absorb light and only 'L' absorbs, t...

Which of the following compounds will be suitable for Kjeldahl’s method for nitrogen estimation?

Sodium salt of an organic acid ‘X’ produces effervescence with conc. H2SO4. ‘X’ reacts with the acidified
aqueous CaCl2 solution to give a white precipitate which decolourises acidic solution of KMnO4. ‘X’ is :
