Question

reducing character increases from hf to hi. Why?

Answer 1

Due to decrease in bond dissociation enthalpy with the increase in atomic size and bond length. Hence reducing character increases from HF to HI.

Answer 2

Reason for an increase of reducing character from HF to HI

Explanation:

• The agent which can donate electrons they are called as reducing character.
• The atomic size of halogens increases from top to bottom. Due to this the length of the bond increases.
• It means that the bond length of HF will be less and HI has more.
• As the bond length is more, the bonds can be broken easily and the compound can be reduced and donate an electron.
• Thus due to the above said reasons reducing character increases from HF to HI.
