Neet 2005 PYQ Free Mock Test

Assertion : Reaction of ${\text{SO}}_2$ and ${\text{H}}_2\text{S}$ in the presence of ${\text{Fe}}_2{\text{O}}_3$ catalyst gives elemental sulphur.Reason : ${\text{SO}}_2$ is a reducing agent.

Assertion : ${\text{SiF}}_6^{2-}$ is known but ${\text{SiCl}}_6^{2-}$ is not.Reason : Size of fluorine is small and its lone pair of electrons interacts with $d$ -orbitals of $\text{Si}$ strongly.

Assertion : Borax bead test is not suitable for $\text{Al(III)}$.Reason : ${\text{Al}}_2{\text{O}}_3$ is insoluble in water.

Assertion : Ozone is a powerful oxidising agent in comparison to ${\text{O}}_2$.Reason : Ozone is diamagnetic but ${\text{O}}_2$ is paramagnetic.

Assertion : Potassium ferrocyanide is diamagnetic whereas potassium ferricyanide is paramagnetic.Reason : Crystal field splitting in ferrocyanide ion is greater than that of ferricyanide ion.
