उत्तर
(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.
