Decreasing order of reactivity of HX in the reaction
`ROH + HX to RX + H_(2)O`

A

`HI gt HBr gt HCl gt HF`

B

`HBr gt HCl gt HI gt HF`

C

`HCl gt HBr gt HI gt HF`

D

`HF gt HBr gt HCl gt HI`

Text Solution

Verified by Experts

The correct Answer is:
A
`HI gt HBr gt HCl gt HF`
(Order of reactivity
HI is more reactive as bond dissociation energy is less due to formation of weak bond (uncomparable size).
