Why HI is most reactive towards alcohol?
Answer: HI has the lowest bond dissociation energy due to longer bond length that’s why it is most reactive.
Why HI is more reactive than HCl and HBr?
The same reasoning applies for both HBr and HI. These acids are even stronger than HCl because the Br– and I– ions are even larger. As such, the H-Br and H-I bonds are even weaker, and these compounds also readily dissociate in solution.
Is HI more reactive than HCl?
The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive).
Which is more reactive HI or HBr?
So in this case, H—I has greater bond length than H—Br (due to greater size of I than Br) so it is easy to cleave H—I bond which makes HI more acidic than HBr.
Which one is more reactive HF or HI?
Which is more reactive towards the reaction with HI?
Among HI, HBr and HCl, HI is most reactive towards alcohols.
Which of the following alcohol has the highest order of reactivity with hydrochloric acid?
The order of reactivity of alcohols is 3° > 2° > 1° methyl. The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive).
Which among HI is most reactive towards alcohols?

What is the difference between HCl HBr and Hi?
HCl, HBr and HI are all strong acids, they are all completely ionized in water. Therefore, you can’t say that one is “stronger” than another when they are all at the same level. Only HF is a “weak” acid, and that is because of the strong attraction between H and F.
What is the nature of acidic nature of Hi and HBr?
Acidic nature depends on how easily the acid can release H+ ion in its aqueous state. In case of HI and HBr, the release of H+ is possible only when H—I or H—Br bond is cleaved or broken. More easily the bond is cleaved, more easy is the release of H+ ion, more acidic is the compound.
What are the best alcohols for conversion to alkyl halide?
Tertiary alcohols work the best for acid catalyzed conversion to alkyl halides. The reaction goes by an SN1 mechanism, but the carbocation is “very” stable and there is usually no problem of rearrangement:
