12 Questions
What characteristic of transition metals is associated with their catalytic activity?
Variable oxidation states
Why do transition metals show catalytic activity?
They exhibit variable oxidation states
Is Copper a non-element?
No, because it has completely filled s-orbitals
In the context of conductivity, why does the conductivity decrease upon dilution of an electrolyte?
The number of ions per unit volume decreases
What is the formula of the complex 'dichloridobis (ethane-1, 2-diamine) platinum(IV) nitrate'?
[Pt (en) (NO)
Which property of transition metals allows them to provide new reaction pathways with lower energy?
Variable oxidation states
What is the IUPAC name of the complex [Pt Cl₂(en)) (NO3)2]?
Dichloridobis(ethane-1,2-diamine)platinum(IV) nitrate
Which statement about osmotic pressure as a colligative property is true?
Osmotic pressure depends on the molar concentration of the solution.
Why is nucleophilic substitution easier in iodoethane compared to chloroethane?
Iodine is a better leaving group due to its large size.
In the presence of incompletely filled d-orbitals, what is the common oxidation state of copper?
$Cu^{3+}$
Why does iodine exhibit a faster rate of nucleophilic substitution compared to chlorine?
Iodine has a larger size and is a better leaving group.
What happens to the total vapor pressure when equal moles of liquid X and Y are mixed to form an ideal solution?
Total vapor pressure increases above the sum of the individual vapor pressures of X and Y.
