Question
Which of the following cannot be regarded as molecular solid?
(i) SiC (Silicon carbide)
(ii) AlN
(iii) Diamond
(iv) I2
Solution
(i) SiC (Silicon carbide)
(ii) AlN
(iii) Diamond
Explanation:
SiC, AIN and diamond are examples of network solid as they have three-dimensional structure while, I2 is a molecular solid, because such solid particles are held together by dipole-dipole interactions. SiC and AIN are interstitial solids.
