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