Solid State Quiz-4

Dear Readers,

The one subject in NEET which is candidates who can easily attain good marks is Chemistry. That's the reason, often, one doesn’t pay notice and choose to compromise it. But if one wants to rank above others, the tip is to be thorough with NEET chemistry concepts. The understanding of reactions and definite basic understanding is what requires major attention in Chemistry but once done it only gets simpler from there. The main focus on the to-do list should be on getting a hang of the NCERT syllabus of NEET chemistry..

Q1. The appearance of colour in solid alkali metal halide is generally due to:
  •  Frenkel defect
  •  Interstitial position
  •  F-centres
  •  Schottky defect
Presence of excess Na in NaCl and there by causing anion vacancy defect makes it yellow, presence of excess Li in LiCl makes it pink and presence of excess K in KCl makes it violet. Greater the number of F-centres, greater is intensity of colour.

Q2.Sodium metal crystallizes in a body centred cubic lattice with the cell edge a=4.29 Å . The radius of sodium atom is :
  •  1.8574 Å
  •  2.8574 Å
  •  3.8574 Å
  •  None of these
Radius of Na(if bcc lattice) =√3/4 a
                                             =√3/4 x 4.29 
                                             = 1.8574 Å 

Q3.  Schottky defect is noticed in :
  •   NaCl
  •  KCl
  •  CsCl
  •  All of these
All these show Schottky defect.

Q4. Which is the wrong statement regarding a crystal containing Schottky defect?
  •  Electrical neutrality of the crystal is maintained
  •  Entropy of the crystal increases
  •  The density of the overall crystal remains the same
  •  The density of the overall crystal reduces
When equal number of cations and anions are missing from their position in a crystal lattice so that electrical neutrality is maintained, the defect is called Schottky defect. Due to missing of ions, the overall density of the crystal decreases. Moreover, defect leads to randomness, thus entropy also increases.

Q5.The mass of a unit cell of CsCl corresponds to :
 An unit cell of CsCl having bcc structure consists of 8 atoms at the corner and one atom at centre. Thus, no. of =8 ×1/8=1 and no. of =1×1=1 Thus, no. of CsCl unit per unit cell = 1 

Q6. If the distance between ions in sodium chloride crystal is X pm, the length of
the edge of the unit cell is
  •  4 X pm
  •  X/4 pm
  • X/2 pm
  •  2X pm
In NaCl, the length of the edge of the unit cell is=2× distance between  ions hence, 
a=2X pm.

Q7.possesses :
  •  Face centred cubic
  •  Body centred cubic
  •  Simple cubic
  •  Hexagonal closed packing
 has fcc structure with 8 : 4 co-ordination and has 4 units of CaF2 per unit cell.

Q8. Which arrangement of electron decides ferrimagnetism?
  •  ↑ ↑ ↑ ↑ ↑
  •  ↑ ↓ ↑ ↓
  •  ↑ ↑ ↑ ↓ ↓
  •  None of these
Ferrimagnetism involves magnetic dipoles oriented in parallel and antiparallel direction in unequal number to give some net dipole moment.

Q9.Extremely pure samples of Ge and Si are non-conductors, but their conductivity increases suddenly
on introducing ….in their crystal lattice.
  •  As
  •  B
  •  Both (a) and (b)
  •  None of these
Doping of elements of group 14 (Ge and Si) with group 15 (As) elements produces excess of electrons and shows n -type conduction, the symbol n indicating flow of negative charge in them. Doping of elements of group 14 (Ge and Si)with group 13 (B) elements products hole (electron deficiency) in the crystal and shows P-type conduction, the symbol p indicating flow of positive charge.

Q10. The structure of CsCl crystal is
  •  Body centred cubic lattice
  •  Face centred cubic lattice
  •  Octahedral lattice
  • None of the above
The co-ordination number of sc, fcc and bcc structure are 6,12 and 8 respectively. CsCl has body centred cubic structure having 8 : 8 co-ordination number.
