Order of M.P. of group 14: $\mathrm{C}>\mathrm{Si}>\mathrm{Ge}>\mathrm{Pb}>\mathrm{Sn}$
$\begin{array}{ll}
\text { element } & \text { M.P. }\left({ }^{\circ} \mathrm{C}\right) \\
\mathrm{Z}=6=\mathrm{C} & 3730 \\
\mathrm{Z}=14=\mathrm{Si} & 1410 \\
\mathrm{Z}=32=\mathrm{Ge} & 937 \\
\mathrm{Z}=50=\mathrm{Sn} & 232 \\
\mathrm{Z}=82=\mathrm{Pb} & 327
\end{array}$
