Test: Classification of Crystalline Solids (Old NCERT) - Question 1

Which of the following statements is not correct about molecular crystals?

Detailed Solution: Question 1

Molecular crystals are bad conductors of electricity as the electrons are localised in the bonds.

Test: Classification of Crystalline Solids (Old NCERT) - Question 2

Ionic solids conduct electricity In molten state but not in solid state because

Detailed Solution: Question 2

Ionic solids conduct electricity in molten state since in molten state ionic solids dissociate to give free ions which in solid state are not free to move and are held together by strong electrostatic forces of attraction.

Which of the solids show the following properties?
(i) Electrical conductivity
(ii) Malleability
(iii) Ductility
(iv) Fairly high melting point

Detailed Solution: Question 3

Metallic solids conduct electricity in molten state as well as solid state and are malleable, ductile and have fairly high melting point.
