Which one of the following substances would have the lowest melting point? a) cl2 b) hi c) h2o d) ccl4

chlorine molecule.

Explanation:

The melting point of a substance depends upon the intermolecular interactions present between the molecules of the substance.

Stronger the interactions higher the boiling point and vice versa.

In case of polar compounds the interactions are stronger than non polar compounds.

water (H₂O) is a polar compound and has intermolecular hydrogen bonds between molecules, which makes its melting and boiling point high.

HI is also a polar molecule and has dipole dipole interactions.

CCl₄ has polar bonds but the molecule is non polar due to net zero dipole moment.

Cl₂ is a completely non polar molecule and has only weak london dispersion forces between molecules, thus it has lowest melting point among the given molecules.

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
