The sdipole miment of hydrogen halides decreases form HF to HI. Explain this trend.

Text Solution

Verified by Experts

The dipole moments of the different halogen halides along with the electronegativities of the atoms are given below :

The trends in the dipole moments are fustified on the basis of the difference in the electronegativities of the halongen and the hydrogen atoms because all of them are diatomic molecules. The difference is the maximum in HF while it is least for HI. Therefore, HF bond is maximum polar and the molecule has the maximum in HF while HI has the minimum value since it is least polar.

Which fo the following statements are correct concerning redox propreties ? (i) The reducing power of hydrogen halides increases from hydrogen chloride to hydrogen iodide. (ii) The oxidizing power of halogens decreases from chlorine to iodine. A metal M for which E^(Ɵ) for the half-reaction M^(n+) +n e^(-) hArr M is very negative will be a good reducing agent.
