Which of the following compounds will undergo self aldol condensation in the presence of cold dilute alkali?
An organic compound 'A' has the molecular formula C₃H₆O. It undergoes iodoform test. When saturated with HCl it gives 'B' of molecular formula C₉H₁₄O. 'A' and 'B' respectively are
Irrespective of the source, pure sample of water always yields 88.89% mass of oxygen and 11.11% mass of hydrogen. This is explained by the law of
How many monochlorobutanes will be obtained on chlorination of n-butane?
Which one of the following esters is obtained by the esterification of propan-2-ol with ethanoic acid?
A chemical reaction is catalyzed by a catalyst X. Hence X
A is a higher phenol and B is an aromatic carboxylic acid. Separation of a mixture of A and B can be carried out easily by having a solution
A glass bulb is filled with NO₂ gas and immersed in an ice bath at 0oC which becomes colourless after some time . This colourless gas will be
The Δ H value for the reaction H2 + Cl2 → 2HCl is − 44.12 K.cal. If E1 is the activation energy of the reactants and E2 is the activation energy of the products, then for the above reaction
Calculate the heat of formation Δ H of CO (in kcal) from the following data :

The ratio of cationic radius to anionic radius in an ionic crystal is greater than 0.732. Its co-ordination number is
Which of the following metals exhibits more than one oxidation states?
Out of the given alternatives Fe is only transition element.
Therefore it shows more than one oxidation state (+ 2 and + 3)
This is due to the fact that there is negligible energy difference
