Which of the following has lowest melting point?
- A \(\mathrm{Si}\)
- B \(\mathrm{Ge}\)
- C \(\mathrm{Sn}\)
- D \(\mathrm{Pb}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Sn}\)
Step-by-step Solution
Detailed explanation
On moving down the group, the melting point decreases with the exception of \(\mathrm{Pb}\) whose melting point is slightly greater than that of \(\mathrm{Sn}\). The correct order of melting point is: \(\mathrm{C}>\mathrm{Si}>\mathrm{Ge}>\mathrm{Pb}>\) Sn Hence, \(\mathrm{Sn}\)…
