Answer:

[tex]HF>CH_{2}NH>CH_{3}I>C_{2}H_{6}[/tex]

Explanation:

[tex]NH_{3}[/tex] is an weak base. HF is an weak acid. Hence an acid-base reaction will ocuur between [tex]NH_{3}[/tex] and HF resulting a homogeneous mixture.

[tex]NH_{3}[/tex] is a polar protic molecule. Hence it can form hydrogen bonding with another polar protic molecule [tex]CH_{2}NH[/tex]. Also dipole-dipole attraction force along with london dispersion force exists between [tex]CH_{2}NH[/tex] and [tex]NH_{3}[/tex].

[tex]CH_{3}I[/tex] is a polar molecule. Hence only dipole-dipole attraction force along with london dispersion force operates between [tex]CH_{3}I[/tex] and [tex]NH_{3}[/tex].

[tex]C_{2}H_{6}[/tex] is a non-polar molecule. Hence only london dispersion force exists between [tex]C_{2}H_{6}[/tex] and [tex]NH_{3}[/tex].

So, order of miscibility: [tex]HF>CH_{2}NH>CH_{3}I>C_{2}H_{6}[/tex]

                                   (most)                                (least)

Rank of the given species from most miscible to least miscible in ammonia is HF > CH₂NH > CH₃I > C₂H₆.

What are polar protic solvents?

Polar protic solvents are those solvents in which hydrogen bond is present within the molecule.

Ammonia (NH₃) is a polar protic solvent and miscibility of different species in it is discussed as below:

  • HF is a acid and it easly miscible in base, that's why it shows high miscibility.
  • CH₂NH is also miscible in NH₃, due to the formation of hydrogen bonding between the two molecules.
  • CH₃I is also miscible in NH₃ but with less efficiency, due to its polar nature.
  • C₂H₆ is very less miscible in NH₃, and shows miscibility due to weak london dispersion force.

So, HF is the most miscible and C₂H₆ is least miscible.

Hence correct sequence is HF > CH₂NH > CH₃I > C₂H₆.
