Vedclass · Answer

(D) The melting point of a solid depends on the nature of the forces holding its particles together.$1$. $Ice$ $(H_2O)$ is a molecular solid held by hydrogen bonds,which is relatively weak.$2$. $Dry \, ice$ $(CO_2)$ is a molecular solid held by weak van der Waals forces.$3$. $NaCl$ is an ionic solid with strong electrostatic forces of attraction,having a melting point of approximately $1074 \ K$.$4$. $SiO_2$ (Quartz) is a covalent network solid where silicon and oxygen atoms are linked by strong covalent bonds in a three-dimensional structure. This network requires a very high temperature to break,resulting in a melting point of approximately $1986 \ K$.Therefore,$SiO_2$ has the highest melting point among the given options.
