NUST NET 2 SAMPLE CHEMISTRY QUESTIONS

National University of Sciences and Technology (NUST) is ranked among top engineering universities of Pakistan. NUST was established in 1991, they have many campuses in different cities but their main campus is in Islamabad. NUST was established with a goal of providing quality education to its students and to create better carrier opportunities for them so that they can succeed in their lives. Nust mainly focus on quality education that’s why their fee is quite high but they facilitate poor and needy students through need base scholarship. NUST has earned his status in a very short period of time through their dedication and hard work.

TOPIC:

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.

Topic:

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.

TOPIC:

Gases, Liquids & Solids

QUESTION:

Which of the following properties is anisotropic?

OPTIONS:

  • Melting Point
  • Density
  • Electrical Conductivity
  • Geometrical Shape

CORRECT OPTION:

Electrical Conductivity

EXPLANATION:

Physical properties that depend on the direction are called anisotropic properties. The physical properties of crystalline solids like refractive index, coefficient of thermal expansion, electrical and thermal conductivity, and cleavage plane are anisotropic in nature.
