List the substances nacl, cl2, ch3cl, and ch3cooh in order of increasing strength of intermolecular attractions. list the substances , , , and in order of increasing strength of intermolecular attractions. nacl

The order will be:

Cl₂ < CH₃Cl < CH₃COOH < NaCl

Explanation:

More the polarity in a compound more the intermolecular interactions between the molecules.

Out of the given molecules, NaCl is the ionic compound and will have strong ion -ion interactions thus will have highest order of strength of intermolecular interactions.

Then CH₃COOH may also dissociate to give acetate ion and hydrogen ion thus it will also show ionic interactions but as it is a weak electrolyte it will have less interactions then NaCl

CH₃Cl is slightly more polar than Cl₂ (which is non polar so will have only london dispersion forces which are weakest intermolecular interactions), so CH₃Cl will have dipole dipole interactions

The order will be:

Cl₂ < CH₃Cl < CH₃COOH < NaCl

imma come back to you hold on

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
