SAMPLE NUST NET 2 CHEMISTRY QUESTIONS

ELECTROCHEMISTRY

QUESTION:

The oxidation of oxygen in peroxides is?

OPTIONS:

  • +1
  • -1
  • +2
  • -2

CORRECT OPTION:

-1

EXPLANATION:

Peroxides include hydrogen peroxide, H2O2. This is an electrically neutral compound and so the sum of the oxidation states of the hydrogen and oxygen must be zero.

Gases, Liquids & Solids

QUESTION:

The figure below shows the crystalline structure for which of the following?

OPTIONS:

  • NaCl
  • Diamond
  • Copper
  • Iodine

CORRECT OPTION:

Iodine

EXPLANATION:

As molecules are packed in the crystalline structure, so it must be a crystal for a molecular solid. Amongst the given list only iodine is a molecular solid.

Sets & Functions

QUESTION:

The set of fourth roots of unity are closed with respect to?

OPTIONS:

  • Addition
  • Division
  • Subtraction
  • None of the above

CORRECT OPTION:

Division

EXPLANATION:

Set = {1,-1,i,-i}

Addition: 1 + i is not part of the set;

Subtraction: 1 – i is not part of the set;

Any division operation in the set results in an element which is part of the set. E.g. 1/i = i/i2 = -i. Hence it is closed w.r.t division;

Remember that set of fourth roots of unit are closed w.r.t multiplication and division.

Vector & Equilibrium

QUESTION:

X and Y is the figure below are?

OPTIONS:

  • X = b + c and Y = a + b
  • X = a + c and Y = a – b
  • X = b and Y = a
  • X = b – c and Y = a + b

CORRECT OPTION:

X = b + c and Y = a + b

EXPLANATION:

This is vector addition in 3D space. Use vector addition head to tail rule to get the values of X and Y as shown in the figure below:

A + X = a + b + c therefore X = b + c.

Y is a simple addition of two vectors a and b.

QUESTION:

Which of the following numbers lie on the imaginary axis of the Argand diagram?

  • 8 + 3i
  • 0 +3i
  • 8 + 0i
  • None of the above

CORRECT OPTION:

0 + 3i

EXPLANATION:

Only B has no real part so its lies on the imaginary axis of the Argand diagram.

BASICS OF CHEMISTRY

QUESTION:

Non-stoichiometric compounds are formed by:

  • 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.
