Question

Explain why sodium chloride is a solid at room temperature and pressure while hydrogen chloride is a gas

Answer 1

Chlorine (Cl2) is a gas at room temperature, but sodium chloride(NaCl) is a solid at room temperature. ... It forms a giant lattice due to the strong ionic force of attraction between the similar molecules,(NaCl - NaCl attraction is strong) so they require huge amount of energy(at higher temperature) to break those forces.
