Question

Arrange in decreasing bond enthalpy hf hcl hbr h i

Answer 1

Here in HI, Iodine has the largest size, thus weakest bond with Hydrogen ... acid strength order is HF > HCl > HBr > HI.

The Increasing order of Acidity here will be HF<HCl<HBr<HI. This is because Acidity is actually ...

Acidity means ability to readily give H⁺ ions. The order of the most acidic will ...

F,Cl, Br, I - all belong to the same group. As one goes down the group, the atomic size increases ..

acidity means aap kitni jaldi H+ nikal sakte ho. ab hamaare paas hai. HF flrin has min.

Answer 2

Answer:hf hcl hbr hi

Explanation:as size increases ,acidic strength increases, bond enthalpy decrease.hf has least acidic strength so it has more bond enthalpy.
