Test: General Methods of Preparation - Question 5
Save

 What is the order of reactivity of following halogen acids on alcohols?
HI, HBr, HCl

Detailed Solution: Question 5

The correct answer is Option B.
Longer the bond length, lesser will be dissociation energy and hence, more reactivity. 
Among halogen acids, bond length increases from HCl to HI.
∴ Order of reactivity of halogen acids towards alcohol is
HI > HBr > HCl
