Answer 2

Complete question:

Which solid compound has a low melting point and is soft?

(A) SO2(s)

(B) NaCl

(C) H2O(S)

(D) SiO2​

Complete Answer:

The solid compound that has the lowest melting point is:

(A) SO2 (s)

- The solid SO2 has a melting point of -72°C which is the lowest in the given options.

- SO2 is also a covalent compound and hence it is soft.

- NaCl is a crystalline solid and it has a melting point of 801°C.

- Water is a hydrogen-bonded solid and it has a melting point of 0°C.

- SiO2 is a network solid and it has a melting point of 1710°C.
