Question

If following molecules undergo dimerization then find the value of $\frac{YZ}{X}$ :
(i) ClO3
(ii) OF
(iii) GaH3
(iv) AlCl3
(v) ICl3
(vi) BeH2
(vii) NO2
Where : X = Number of molecules which are hypervalent in dimeric form.
Y = Number of molecules which complete octet in dimer form
Z = Number of molecules which are hypovalent in dimeric form

Correct answer: 3 / X = 2 (I2CL6, CL2O6), Y = 3 (O2F2, AL2CL6, N2O4), Z = 2 (GA2H6, BE2H4).<BR>VALUE OF $\FRAC{YZ}{X} = \FRAC{3 \TIMES 2}{2} = 3$. Step 1: Molecular solids are composed of discrete molecules held together by weak intermolecular forces, rather than giant covalent networks, metallic bonds, or ionic lattices. Step 2: Buckminsterfullerene (C60) exists as discrete geodesic spheres (buckyballs) held together by weak van der Waals forces in the solid state. Step 3: Thus, C60 is a molecular solid, making option (b) the correct answer.
