Which of the following will not be soluble in sodium carbonate solution?
While 2,4,6-trinitrophenol, benzoic acid and benzene sulphonic acid are soluble in NaHCO3.This reaction is possible in the forward direction if acid is more acidic than H2CO3.o-nitrophenol is less acidic than H2CO3.Hence, it is not soluble in sodium hydrogen carbonate.
Which of the following reactions is used for detecting presence of carbonyl group ?
Which of the following expressions gives the de-Broglie relationship?
The total number of electrons present in all the ρ-orbitals of bromine is
A compound possesses 8% sulphur by mass. The least molecular mass is
The compound with carbon uses only its sp3 hybrid orbitals for bond formation is
Which of the following gives maximum energy in metabolic process?
A negatively charged nucleophile is always stronger than a neutral one
Among the following the bond with highest bond dissociation energy is
The enthalpy change (∆H) for neutralisation of 1 M HCl by caustic soda in dilute solutions at 298 K is
A and B are gaseous substances which react reversibly to give two gaseous substances C and D,accompanied by the liberation of heat.When the reaction reaches equilibrium,it is observed that Kp = Kc.The equilibrium cannot be disturbed by
The rate constant of first order reaction whose half life is 480 sec is
Which of the following elements has the lowest ionisation potential
The ionisation potential increases from O to F to Ne, because of increasing nuclear charge. The ionisation potential is highest for Ne because of its stable (ns2 np6) electronic configuration. But the ionisation potential of O is lower than N although the nuclear charge of O is higher. This is due to the extra-stability of exactly half-filled 2p-orbitals of N.
A system is said to be in thermodynamic equilibrium when it is in
The detergents which are most suitable for cleansing synthetic fibres, are
The IUPAC name of Na3[Co(N02)6] is sodium hexanitro cobaltate (III).

Of the following which is paramagnetic and has three electron bond in its structure
In which one of the following compounds, the oxidation number of sulphur is the least
A metal X on heating in nitrogen gas gives Y, Y on treatment with H₂O gives a colourless gas which when passed through CuSO₄ soution gives a blue colour. Y is
