Solid \(C{O_2}\) is an example of
1 Molecular crystal
2 Ionic crystal
3 Covalent crystal
4 Metallic crystal
Explanation:
\(1.\) These are the substances that are having relatively the weaker intermolecular binding force. \(2.\) These molecular crystals are soft having he low melting point. \(3.\) They are the poor conductor of the heat as well as the electricity. \(4.\) Solid Carbon dioxide is also known as the dry ice. \(5.\) The constituent particles in the solid Carbon dioxide are the molecules which are bound together forming the layers by the weak intermolecular forces. Therefore, Solid \(CO _2\) is an example of Molecular crystal.
The Solid State

Value of heat of fusion of \(NaCl\) is
1 Very low
2 Very high
3 Not very low and not very high
4 None of the above
Explanation:
\((b)\) The value of heat of fusion of \(NaCl\) is very high due to \(fcc \) arrangement of its ions.
