Conductivity of a saturated solution of a sparingly soluble salt AB at 298 K is 1.85 10-6 Sm-1. Solubility product of the salt AB at 298 K is
(Given, (AB) = 140 Sm2 mol-1)
5.7 × 10-12
1.32 × 10-12
7.5 × 10-12

The statement that is not correct is
Compressiblity factor measures the deviation of real gas from ideal behaviour
Van der Waals constant 'a' measures extent of intermolecular attractive forces for real gases
Cnlical temperature is the lowest temperature at which liquefaction of a gas first occurs
Boyle point depends on the nature of real gas
The correct arrangement for the ions in the increasing order of their radii is
Na+, Cl-, Ca2+
Ca2+, K+, S2-
Na+, Al3+, Be2+
Cl-, F-, S2-
The correct arrangement of the species in the decreasing order of the bond length between carbon and oxygen in them is
CO, CO2, HCO, CO
CO2,CO, CO, HCHO
CO, HCO, CO2, CO
CO, CO, CO2, HCO
C.
CO, HCO, CO2, CO
The correct arrangement of the species in the decreasing order of the bond length between carbon and oxygen in them is CO2, CO.
For the properties mentioned, the correct trend for the different species is in
strength as Lewis acid - BCl3 > AlCl3 > GaCl3
inert pair effect - Al > Ga > ln
oxidising property - Al3+ > ln3+ > Ti3+
first ionization enthalpy - B > Al > Ti
A correct statement is
[Co(NH3)6]2+ is paramagnetic
[MnBr4]2- is tetrahedral
[CoBr2(en)2]- exhibits linkage isomerism
[Ni(NH3)6]2+ is an inner orbital complex
