Transition Elements

QUESTION

Transition elements from complexes due which of the following reason?

OPTIONS

  • Para magnetism
  • Vacant d-orbitals
  • Large nuclear charge
  • Small cation size

CORRECT OPTION

Vacant d-orbitals

EXPLANATION

Vacant orbitals of central metal atom or iron are filled by ligands to form metal complexes.

In Chemistry, a coordination complex or metal complex consists of a central atom or ion which is usually metallic and is called the coordination center and a surrounding array of bound molecules or ions that are in turn known as ligands or complexing agents. Many metal containing compounds, especially those of transition metals are coordination complexes.

Reaction Kinetics

Question

For homogeneous catalysis reaction between liquids, the catalyst should be of which form?

Options

  • Solid
  • Liquid
  • Gas
  • Can be any of the above

Correct Answer

Liquid

Explanation

In chemistry, homogeneous catalysis is a sequence of reactions that involve a catalyst in the same phase as the reactants. Phase here refers to solid, liquid, vs gas. Most commonly, a homogeneous catalyst is co-dissolved in a solvent with the reactants.

Basics of Chemistry

QUESTION

Non-stoichiometric compounds are formed by:

OPTIONS

  • Only alkali metals
  • Only transition elements
  • Only noble gases
  • None of the above

CORRECT OPTION

Only transition elements

EXPLANATION

Binary transition metal compounds, such as the oxides and sulfides, are usually written with idealized stoichiometry’s, such as FeO or FeS but these compounds are usually cation deficient and mostly never contain a 1:1 cation:anion ratio. Thus a substance such as ferrous oxide is actually a nonstoichiometric compound with a range of compositions.
