A compound can crystallise in two forms \(\alpha\) and \(\beta\) which are fcc and bcc, respectively. The \(\alpha\)-form has side length of \(2 \mathrm{pm}\) and the \(\beta\)-form has side length of \(4 \mathrm{pm}\). The ratio of their density \(\frac{\rho_\alpha}{\rho_\beta}\) i
- A 32
- B 16
- C 8
- D 4
Answer & Solution
Correct Answer
(B) 16
Step-by-step Solution
Detailed explanation
Density \(\left(\rho_\alpha\right)\) for \(\alpha\)-form \(=\frac{M Z_1}{N_0\left(a_1\right)^3}\) and density \(\left(\rho_\beta\right)\) for \(\beta\)-from \(=\frac{M Z_2}{N_0\left(a_2\right)^3}\) Given, side length \(\left(a_1\right)\) for \((\alpha)=2 \mathrm{pm}\) side…
