Question 1
1 / -0

Which of fallowing has different structure than other?

A
NaCl

B
LiCl

C
RbCl

D
CsCl

Solution
Question 2
1 / -0

All of the following share the same crystal structure except :

A
$$LiCl$$

B
$$NaCl$$

C
$$RbCl$$

D
$$CsCl$$

Solution
Question 3
1 / -0

Which of the following is an interstitial compound?

A
$$ PdCl_2 $$

B
$$ NH_3 $$

C
$$ZnO$$

D
$$TiH$$

Solution

An interstitial compound is a compound that is formed when an atom with a small enough radius sits in an interstitial hole in a metal lattice. Examples of small atoms are boron, carbon and nitrogen. These compounds play an important role in industries. Examples: $$TiH$$, $$Fe_3H$$ and $$Mn_4N$$
Question 4
1 / -0

The total number of lattice arrangements in different crystal systems is:

A
$$14$$

B
$$8$$

C
$$3$$

D
$$7$$

Solution

The seven basic crystal lattice arrangements are :- Cubic, Tetragonal, Orthorhombic, Monoclinic, Hexagonal, Rhombohedral and Triclinic.
Question 5
1 / -0

Which primitive unit cell has unequal edge lengths ($$a \neq b \neq c$$) and all axial angles different from 90?

A
Tetragonal

B
Hexagonal

C
Monoclinic

D
Triclinic

Solution

In Triclinic cell
$$a \neq b \neq c\ \&\ \alpha \neq \beta \neq \gamma \neq 90^o$$.
Question 6
1 / -0

The empty space between the shaded balls and hollow balls as shown in the diagram is called

A
hexagonal void

B
octahedral aoid

C
tetrahedral void

D
double triangular void

Solution

Question 7

1 / -0

Match the List -I (reduction process) with List - II (element).

List -I (reduction process)	List - II (element)
(P) Number of occupied O.V. in diamond unit -cell	(1) 2
(Q) Coordination no.of $$ S^{2-}$$ in zinc blend structure	(2) 6
(R)$$ _{ 92 }^{ 238 }{ U\rightarrow _{ 82 }^{ 214 }{ Pb } } $$, number of $$ \alpha $$ - particles given out	(3) 4
(S) $$ _{ 13 }^{ 29 }{ Al }\rightarrow _{ 13 }^{ 27 }{ Al } $$ , number of $$ \beta $$ particles given out	(4) 0

P-4 Q-2 R-3 S-1

P-2 Q-4 R -1 S-3

P-4 Q-3 R -2 S-1

P-2 Q-4 R -3 S-1

Question 8
1 / -0

An element X (A.w =80 g/mol) having fcc structure.Calculate the number of unit cells in 8g of X:

A
$$0.4 \times N_4$$

B
$$0.1 \times N_4$$

C
$$4 \times N_A$$

D
$$N_A /40$$

Solution
Question 9
1 / -0

How many molecules are there in the unit cell of sodium chloride?

A
$$2$$

B
$$4$$

C
$$6$$

D
$$8$$

Solution

In $$NaCl$$ (rock salt):

Number of $$Na^{+}$$ ions $$= 12$$ (at edge centers) $$\times \dfrac {1}{4} + 1$$ (at body centre) $$\times 1 = 4$$.

Number of $$Cl^{-} ions = 8$$ (at corners) $$\times \dfrac {1}{8} + 6$$ (at face centre) $$\times \dfrac {1}{2} = 4$$.

Thus $$4$$ formula units per unit cell.
Question 10
1 / -0

Crystals can be classified into .......... basic crystal habits.

A
$$7$$

B
$$4$$

C
$$14$$

D
$$3$$

Solution

The structures of all crystals can be classified according to the symmetry of the unit cells. There are in total 7 groups, collectively called Crystal Systems: Tricinic, Monoclinic, Orthorhombic, Tetragonal, Trigonal, Hexagonal, and Cubic

Hence A is correct option
